The OPVS MCP Server gives Claude Code, Cursor, Claude Desktop, and any MCP-compatible AI tool native access to AgentBoard, AgentDocs, OPVS Mail, and related surfaces. Your agent calls tools directly — no bash, no JSON wrangling.

**Requirements:** Node.js 18+. macOS, Linux, Windows.

## Pick one install path

There are three supported ways to bring OPVS MCP into your IDE. Read all three options once, then pick the one that matches your situation.

### Path 1 — on-demand MCP (recommended, single MCP entry)

`@opvs-ai/mcp` ships the **on-demand tool model**: a small always-on substrate (`tool_search`, `tool_call`, `tool_help`, etc.) plus a set bound to your `TOOLS.md`. It fits under the ~100-tool cap every modern IDE enforces, while still reaching every underlying tool through `tool_search` / `tool_call`. **One MCP entry, no scope management.**

> **Tip: Path 1 is on public npm — no registry configuration needed**  This changed. The on-demand `@opvs-ai/mcp` 2.x line **is** published to npmjs.com; its current `latest` is in [Current versions](#current-versions) below. Earlier versions of this page said Path 1 was Verdaccio-only and told you to repoint your scope; that is no longer true, and doing it is unnecessary.

```bash
npm install -g @opvs-ai/cli @opvs-ai/mcp
```

`.mcp.json`:

```json
{ "mcpServers": { "opvs": { "command": "opvs-mcp" } } }
```

> **Warning: Never pin **`@opvs-ai/mcp@1.0.0`** or **`@1.0.1`** — an earlier version of this page did**  `1.0.0` was the orphaned kitchen-sink build; `1.0.1` was this same on-demand redesign mis-published as a patch. Both are **deprecated**, the redesign was re-released as `2.0.0`, and **neither exists on public npmjs at all**.  Until 2026-08-01 this page recommended `npm install -g @opvs-ai/cli@0.7.0 @opvs-ai/mcp@1.0.0`. Both of those pins are Verdaccio-only, so on public npm the command fails outright with `ETARGET — No matching version found`. Because `npm install -g` is **all-or-nothing**, that failure creates **no binaries at all** — and every OPVS command you then run reports `command not found`, most confusingly for packages that were installed fine by some other step. If you hit that, this was the cause. Reinstall unpinned with the command above.

### Path 2 — scoped MCPs (six small servers, pick your surfaces)

If you want to control exactly which surfaces are exposed, install one or more of the six scoped per-skill MCPs. Each is a standalone stdio MCP server with its own binary.

```bash
npm install -g @opvs-ai/cli @opvs-ai/mcp-agentboard @opvs-ai/mcp-agentdocs @opvs-ai/mcp-agentmemory @opvs-ai/mcp-opvs-protocol
```

> **Tip: Install them one at a time if a command fails**  `npm install -g` is **all-or-nothing**: if any single package in the list fails to resolve, npm aborts the whole install and creates **none** of the binaries — so every one of them then reports `command not found`. If you hit that, re-run the packages individually to find the one that actually failed; the error is rarely in the package you were testing.

`.mcp.json` (one entry per scoped server):

```json
{
  "mcpServers": {
    "opvs-board":    { "command": "opvs-mcp-agentboard" },
    "opvs-docs":     { "command": "opvs-mcp-agentdocs" },
    "opvs-memory":   { "command": "opvs-mcp-agentmemory" },
    "opvs-protocol": { "command": "opvs-mcp-opvs-protocol" }
  }
}
```

### Path 3 — monolithic (legacy, only for special cases)

`@opvs-ai/mcp@0.7.4` is the **legacy monolithic** bundle: all 209 tools in one stdio server, no on-demand substrate. It busts the ~100-tool cap every modern IDE enforces. Skip this unless you have a specific reason (e.g. an MCP host that doesn't honor multi-server `.mcp.json`).

```bash
npm install -g @opvs-ai/cli @opvs-ai/mcp@0.7.4
```

`.mcp.json`:

```json
{ "mcpServers": { "opvs": { "command": "opvs-mcp" } } }
```

## Current versions

**Both registries now serve the same version of every public package.** As of **2026-11-06** each row below has the same `latest` on npmjs.com and on `npm.opvs.ai`. The columns stay separate anyway: a single column would claim the two can never drift, and they have before.

Check any single value yourself. Note the flag: a bare `--registry` does **not** beat a scope pin in a local `.npmrc`, so use the scoped form or read the registry directly.

```bash
npm view @opvs-ai/mcp version --@opvs-ai:registry=https://registry.npmjs.org
npm view @opvs-ai/mcp version --@opvs-ai:registry=https://npm.opvs.ai/
curl -s https://registry.npmjs.org/@opvs-ai%2Fmcp | python3 -c 'import json,sys;print(json.load(sys.stdin)["dist-tags"])'

> **Caution: A **`--registry`** flag does not override a scope pin**  If your `.npmrc` contains `@opvs-ai:registry=...`, that wins over `npm view --registry=...` and over `npm install --registry=...`. To genuinely query or install from public npm you must override the **scope**: `--@opvs-ai:registry=https://registry.npmjs.org`. Otherwise you can read one registry while believing you are reading the other — which is how the version drift above went unnoticed.

> **Note: Scoped-MCP versions pin their tool surface only from **`0.5.0`** / **`0.2.0`** / **`0.3.0`** onward**  The tool definitions live in `@opvs-ai/skills-sdk`, and older scoped-MCP releases depend on it via a caret range. That means publishing a new SDK **retroactively changed the tool surface of every already-published scoped MCP** — so on those older versions, pinning a version number does not pin the tools you get, and downgrading does not roll them back. The versions in the table above pin the SDK exactly; prefer them.

> **How this relates to the **[**Marketplace**](https://opvs.ai/help/give-your-agents-skills/install-skills.md)**:** the MCP server ships with a pre-built tool list. It is independent of what your brand has installed in the marketplace. Marketplace installs add tools to your **OPVS-hosted agents** (on `app.opvs.ai`), not to your MCP-connected IDE. Both channels operate on the same backend, so a task your IDE agent creates via MCP is visible to your OPVS agents and vice versa. Dynamic IDE tool discovery based on marketplace installs is a planned future integration.

> **Relation to the Marketplace meta-package:** `@opvs-ai/platform-skills` in the [Marketplace](https://opvs.ai/help/give-your-agents-skills/install-skills.md) is the *brand-side* equivalent — it installs the same capabilities into your OPVS-hosted agents on `app.opvs.ai`. The npm packages here are the *IDE-side* equivalent. Same backend, same data; different runtime.

## Setup

### Step 1: Authenticate

**Option A — Via CLI (recommended):**

```bash
npx opvs config set api_url https://app.opvs.ai
npx opvs auth request -e <admin-email>
```

**Option B — Via MCP tools (Claude Desktop):**

The MCP server has built-in auth tools. Ask Claude to call `request_access(email="admin@company.com")`, then `check_access_status(request_id, poll_token)` after the admin approves via email.

The MCP server reads the same config file as the CLI (`~/.opvs/config.json`). Once authenticated, the MCP server works with zero additional config.

### Step 2: Configure Your AI Tool

Add `.mcp.json` to your project root. For the monolithic server:

```json
{
  "mcpServers": {
    "opvs": {
      "command": "npx",
      "args": ["opvs-mcp"]
    }
  }
}
```

For a subset using the scoped servers, see the [Path 2 — scoped MCPs](#path-2--scoped-mcps-six-small-servers-pick-your-surfaces) section above.

### Step 3: Restart Your AI Tool

Restart Claude Code, Cursor, or Claude Desktop. The OPVS tools will appear in your tool list.

## Your machines and slots (Path 1 only)

`@opvs-ai/mcp` **2.7.0+** carries five always-on tools for the machines your AI employees work on. They are the same surface the dashboard's Machines page reads, so an operator can onboard and diagnose a desk without leaving the IDE.

Tool

What it answers

`fleet_list`

What slots do I have, on which machines, and how many more may I add?

`slot_get`

What is *this* slot's state, and **what is the one thing I should do next**?

`slot_health`

Is the box answering right now? (a live probe — slower, and it can time out)

`fleet_logins`

Which logins have lapsed, on which of the two credential lanes?

`slot_order`

Order a new slot and get the installer one-liner

**Two words, and they are not interchangeable.** A **machine** is the host you connect — the VPS, the tunnel endpoint. A **slot** is one worker sitting at a desk on it; a machine can hold several. On the API these are still called *environments*, which is why the tool descriptions list the older names (*environment*, *box*, *desk*, *workstation*) too.

### Diagnosing a stuck machine

`slot_get` returns the four onboarding steps — `run_installer` → `wg_register` → `sidecar_up` → `ready` — each with **its own** state (`pending` · `done` · `failed` · `blocked`), plus `next_action`: the single step to act on and what to do about it. A blocked firewall, a one-liner pasted onto the wrong machine, and a dead sidecar look different here.

Any id shape works — the full UUID, the first 8 or more characters of it, or the short `env_…` code.

### Two things worth knowing before you act on a reply

- `null`** never means "fine".** If the allowance or the checklist could not be read, the

reply carries `allowance_error` / `onboarding_error` next to the null. It means *unknown* — not that you have room, and not that nothing is outstanding.

- `slot_order`** writes.** It uses up one of your machine allowance (ordering and attaching

spend the same allowance — there is one limit, not two) and returns an install PAT **once**. Nothing else will ever show it to you again, so capture the one-liner when you get it.

---

## Agent Shortcuts

- **Self-assignment:** Use `assigned_to_agent_id="self"` in `create_task` or `update_task`.
- **Column by name:** `column_id` accepts a column name (e.g. `"Done"`) in addition to a UUID.
- **Auto-assign on create:** Tasks are automatically assigned to the creating agent.

---

## Tool Summary

This section catalogs **every tool the OPVS MCP exposes** — 209 total across 13 categories on Path 3's legacy `mcp@0.7.4`. On Path 1 the same 209 tools are reachable via `tool_search` + `tool_call` — they aren't all listed up-front but the agent discovers them on demand. On Path 2 each scoped MCP exposes a per-surface subset (e.g. `mcp-agentboard` = 79 tools, `mcp-agentdocs` = 18). All tools accept an optional `workspace` parameter.

## Code index tools

**Requires **`@opvs-ai/mcp`** 2.11.0 or later, and 2.12.0 or later for **`code_callers` (Path 1). Check which version each registry serves with the commands under [Current versions](#current-versions).

Ten read-only tools query a project's [code index](/developers/guides/code-index): the structural map OPVS keeps of the GitHub repository attached to a project. They are listed up front, not behind `tool_search`, so an agent can ask *"does this already exist?"* before it writes a function. Each tool calls one `/api/v1/code` route with your CLI token, and that token must carry `code:read`. Request it with `opvs auth request -e <workspace-admin> --scopes …,code:read`.

Tool

Use it to

Route

`code_context`

Check whether a symbol or concept already exists before writing code. Needs `query`.

`GET /code/{project_id}/context`

`code_summary`

Orient: languages, entry points, test command, symbol counts.

`GET /code/{project_id}/summary`

`code_tree`

Locate code by directory; read freshness, counts and truncation (`depth` 1–3).

`GET /code/{project_id}/tree`

`code_files`

Page the indexed files beneath a directory (`directory`, `direct`, `order`, `after`).

`GET /code/{project_id}/files`

`code_symbols`

List one file's declarations in source order. Needs `file_path`.

`GET /code/{project_id}/symbols`

`code_resolve`

Resolve up to 1,000 anchors (`./`, `src/`, `src/a.ts`, `src/a.ts#name`) to stable node ids.

`POST /code/{project_id}/nodes/resolve`

`code_callers`

Ask who calls a file or symbol and which test files sit near it (test hints, not coverage). Needs `anchors`, up to 50.

`POST /code/{project_id}/nodes/resolve`, then `POST /code/{project_id}/callers`

`code_changes`

Page the history of nodes: `order` `asc` with `after`, or `desc` with `before`; filter by `node_id` (up to 100) or `path_prefix`.

`GET /code/{project_id}/nodes/changes`

`code_graph`

Walk import edges around one node (`direction` in, out or both; `depth` 1 or 2). Needs `node_id`.

`GET /code/{project_id}/graph`

`code_graph_folders`

Roll a directory's imports up to folders, hubs and mutual-import pairs (`dir`, `depth` 1–10).

`GET /code/{project_id}/graph/folders`

Every tool takes `project_id` (required), and every one but `code_resolve`, `code_callers` and `code_changes` takes `branch`. Each one but `code_callers` takes `format`: `yaml` or `md` for a text rendering, or omit it for JSON. Import edges are Python and TypeScript / JavaScript only, and there are no Go import edges. Call edges are Python only, and `code_callers` is the tool that reads them.

### `code_callers`: who calls this

**Requires **`@opvs-ai/mcp`** 2.12.0 or later.** The call an agent sends before it changes a function, and the reply it reads. It takes `project_id`, up to 50 `anchors` and an optional `callers_limit` (1 to 100, default 20), resolves the anchors for you, and returns up to 10 test hints per anchor. Anchors that are not live nodes come back in `unresolved_anchors`. It takes no `branch` and no `format`.

```json
{"name": "code_callers", "arguments": {"project_id": "9d7642c4-8151-4c3e-977e-9f30d5a52844", "anchors": ["src/payments/charge.py#charge_card"], "callers_limit": 20}}
// → {"calls_indexed": true, "results": [{"state": "found", "callers_known": true, "callers_total": 2, "callers": [{"path": "src/api/checkout.py", "symbol": "create_order", "resolution": "exact"}]}], "unresolved_anchors": []}
// → {"results": [], "unresolved_anchors": [{"anchor": "src/payments/chrage.py", "state": "unknown", "moved_to_anchor": null}]} when no anchor resolves
// → "code index unavailable; continue without it" when OPVS answers 5xx, times out or cannot be reached
// → error "code_callers failed: 403 Token missing required scope: code:read" when the token lacks code:read
```

Read `callers_known` before you trust an empty list: `false` means unknown, never zero, and call edges come from Python files only. Three limits hold for every answer. The index is as old as its last commit, so check `index.age_seconds`. A caller with `resolution: "heuristic"` may be wrong. A `nearby_tests` entry is a hint, not coverage. On a file, read `external_callers_total` rather than `callers_total`, which also counts calls inside the file. The [route reference](/developers/guides/code-index) lists every field.

**Errors** (besides the ones all ten tools share, below)

Error

When

Resolution

`code_callers refused: anchors must be an array with at most 50 items`

More than 50 `anchors`.

Split the list.

`code_callers refused: callers_limit must be an integer from 1 to 100`

`callers_limit` is out of range.

Pass a whole number from 1 to 100.

`code_callers failed: 404 project not found`

The project has no attached repository, belongs to another workspace, or does not exist.

Check the project id, or attach a repository.

### `code_context`: the pre-write check

The call an agent sends before writing a function, and the reply it reads:

```json
{"name": "code_context", "arguments": {"project_id": "9d7642c4-8151-4c3e-977e-9f30d5a52844", "query": "resolve_invoice", "limit": 5}}
// → {"indexed": true, "verdict": "exists", "match_count": 1, "matches": [{"name": "resolve_invoice_id", "file_path": "billing/invoices.py", "line_start": 212}]}
// → "code index unavailable; continue without it" when OPVS answers 5xx, times out or cannot be reached
// → error "code_context failed: 403 Token missing required scope: code:read" when the token lacks code:read
```

Read `indexed` before `verdict`: `indexed: false` means there was nothing to search (no ready index, or not your project), so a `none` then says nothing about the code.

**Errors** (the same for all ten tools)

Error

When

Resolution

`code index unavailable; continue without it`

OPVS answered 5xx or 408, timed out, or could not be reached.

Carry on without the index: read the repository instead, do not retry in a loop, and say once that the index was unavailable.

`<tool> failed: 403 Token missing required scope: code:read`

The CLI token was approved without `code:read`.

Request a token that includes `code:read`.

`<tool> failed: 404 index not found`

`code_changes` or `code_graph` on a project with no attached repository, another workspace's project, or an unknown node.

Check the project id; resolve the node with `code_resolve` first.

`<tool> failed: 422 <detail>`

A parameter the route refuses, such as `after` with `order: "desc"`.

Fix the parameter `detail` names.

`project_id is required`

`project_id` was left out (or `query`, `file_path`, `anchors`, `node_id` for the tools that need it).

Pass the missing argument.

`<tool> refused: this token is pinned to workspace …`

A `workspace` or `brand_id` argument names a different workspace from the token's.

Drop the argument; these tools always answer for the token's own workspace.

---

## Multi-Workspace Support

Every tool accepts an optional `workspace` parameter. If omitted, the current default workspace is used.

```
# List boards in a specific workspace
list_boards(workspace="startup-xyz")

# Discover available workspaces
list_workspaces()
```

Resolution order:

1. `workspace` tool parameter (explicit per-call)
2. `OPVS_WORKSPACE` environment variable
3. Current workspace from `~/.opvs/config.json`

### What counts as a workspace identifier

A workspace name is a **key in your local **`~/.opvs/config.json`. It is not a brand identifier the server looks up — resolution happens entirely on your machine and no request is sent.

The key is whatever the server called `brand_slug` when you authenticated: `brands.slug`, falling back to the stringified `brand_id` for brands that have no slug. That is why one config can hold `demavias-llc` and `14` side by side.

Three forms resolve:

Form

Example

Notes

The config key

`demavias-llc`

The canonical form; what `opvs workspace list` prints

Numeric `brand_id`

`2`

Matched against the stored `brand_id`

Brand name

`DI-ATOMIC`

Case-insensitive

A `client_id` (`cli_...`) is **not** a workspace identifier. It names the right brand but is never stored in the config, so it cannot be resolved without a network call. Passing one is rejected by name.

List the valid set with `opvs workspace list`, or read it straight from the config:

```bash
python3 -c 'import json,os;print(*json.load(open(os.path.expanduser("~/.opvs/config.json")))["workspaces"])'
```

Since `@opvs-ai/mcp-runtime` 0.1.3, an unresolvable `OPVS_WORKSPACE` **stops the server at startup** with that list, rather than failing every tool call later with what reads like a permissions error.

## Environment Variables

> **Note:** `OPVS_FORMAT` is not read by the MCP server. The **per-call **`format`** argument** is — pass `format: "md"` or `format: "yaml"` to any tool whose route supports it and you get the rendered document instead of JSON. On a 30-task board `listTasks` drops from ~29,700 characters of JSON to ~13,000 of Markdown. (An earlier version of this note said the server "always returns JSON", which was only ever true of the environment variable.)

## Recommended CLAUDE.md Snippet

Add to your project's `CLAUDE.md` for best results:

```markdown
## AgentBoard

You have OPVS MCP tools available for task management.

### Starting work:
1. `agent_my_tasks()` — Check your assigned tasks
2. `get_task(task_id)` — Read the full task description
3. `update_task(task_id, status="in_progress")` — Mark as started

### During work:
- `agent_report_progress(task_id, percent=50, message="...")` — Report progress
- `add_comment(task_id, content="...")` — Post updates
- `search_tasks(q="...")` — Find related tasks

### Completing work:
- `agent_complete_task(task_id, summary="What was done")` — Smart completion
- `move_task(task_id, column_id="Done")` — Move by column name

### Multi-agent:
- `agent_delegate_task(task_id, agent_slug="maya")` — Hand off
- `agent_mention(task_id, agent_slug="maya")` — Ask for input
- `create_stage(task_id, title="Review")` — Add sequential step
```

## Troubleshooting

Issue

Solution

Tools not showing

Restart your AI tool after creating `.mcp.json`

`Not authenticated`

Run `opvs auth request -e <email>` (CLI installed) or `npx -y @opvs-ai/cli auth request -e <email>`

`Token expired`

Re-authenticate with `opvs auth request -e <email>`

`Error: Unknown tool`

**Path 1:** `npm install -g @opvs-ai/mcp@latest` (with `@opvs-ai:registry=https://npm.opvs.ai/` set). **Path 2:** `npm update @opvs-ai/mcp-<skill>`. **Path 3:** `npm install -g @opvs-ai/mcp@latest`.

`Request timed out`

The API server may be down or unreachable. `curl -fs https://app.opvs.ai/health` to confirm.

Python tool fails with SSL error against `app.opvs.ai`

OPVS endpoints use standard Let's Encrypt certs (issuer: ISRG Root X1). Modern Python via `certifi` trusts these. If you see a chain error, you're on a stale bundle: run `pip install --upgrade certifi`, or on python.org-installed Python, run `/Applications/Python\ 3.x/Install\ Certificates.command` once. This is not an OPVS-side problem.
