Run this in your terminal

claude mcp add productbrain --env PRODUCTBRAIN_API_KEY=your-value --env PRODUCTBRAIN_PROJECT_ID=your-value --env PRODUCTBRAIN_API_URL=your-value -- npx -y @productbrain-com/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Common questions

Is ProductBrain safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PRODUCTBRAIN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

ProductBrain MCP server

Drive your ProductBrain plan from an MCP client — Claude Desktop, Cursor, Claude Code — with tools for search, read, mutate, the methodology workflow, and the live view.

Design — a thin shim, on purpose

This server is a thin transport over ProductBrain's versioned v1 REST API. Each tool is one call to an existing /api/v1 endpoint. The REST contract stays canonical:

It's stable when the MCP spec churns — the contract you depend on is the frozen v1 API, not the protocol.
You can drop to raw HTTP or bring your own LLM at any time; MCP is one front-door, not the only one.
Responses carry the same in-band _meta coaching the API returns, so your agent self-corrects.

Install

// Claude Desktop — claude_desktop_config.json

{ "mcpServers": { "productbrain": { "command": "npx", "args": ["-y", "@productbrain-com/mcp"], "env": { "PRODUCTBRAIN_API_KEY": "pb_your_key", "PRODUCTBRAIN_PROJECT_ID": "your-project-id" } } } }

# Claude Code

claude mcp add productbrain \ -e PRODUCTBRAIN_API_KEY=pb_your_key \ -e PRODUCTBRAIN_PROJECT_ID=your-project-id \ -- npx -y @productbrain-com/mcp

Cursor and other clients: add an mcpServers entry with the same command/args/env.

Config (env)

Var	Required	Default
`PRODUCTBRAIN_API_KEY`	yes	— (your `pb_` key from the app's API Key modal)
`PRODUCTBRAIN_PROJECT_ID`	no	— (tools also accept a `projectId` argument)
`PRODUCTBRAIN_API_URL`	no	`https://productbrain.com/api/v1`

Tools

Every agent-facing /api/v1 endpoint has a tool. One tool, one endpoint, same _meta coaching passed back verbatim.

The plan

Tool	Maps to	Use
`search`	`GET /search`	Semantic search — use first for any lookup
`list_nodes`	`GET /nodes`	Bulk read, optional type/iteration filter
`get_tree`	`GET /tree`	A node in context (ancestors/siblings/children/subtree)
`mutate`	`POST /mutate`	Create/update/delete nodes + phases; pass `idempotencyKey` to make retries safe
`list_iterations`	`GET /iterations`	Phases; `current:true` for the active one
`run_workflow`	`POST /workflow`	Story-Mapping methodology (add / task-curate / phase-assign)
`export_okf`	`GET /export-okf`	The plan as a portable OKF file bundle
`get_changelog`	`GET /changelog`	Plan history: every add/update/delete/restore, attributed to the app or a named agent

The view

Tool	Maps to	Use
`set_view` / `read_view`	`POST /view-command`, `GET /view-state`	Drive / read the live canvas

Projects

Tool	Maps to	Use
`list_projects`	`GET /projects`	Projects you own or are a member of; `includeArchived` for the rest
`create_project`	`POST /mutate {addProject}`	Bootstrap a brain — seeds the system "Later" phase. Pass an explicit `id`: `addProject` runs before mutate reads `Idempotency-Key`, so it is not retry-safe
`rename_project`	`POST /mutate {renameProject}`	Change the display name; the id is immutable
`archive_project`	`PATCH /projects`	Hide/unhide without deleting (reversible)

Webhooks

Tool	Maps to	Use
`list_webhooks`	`GET /webhooks`	Registered hooks with `lastStatus` — spot a failing receiver
`create_webhook`	`POST /webhooks`	Register; returns the signing secret once
`update_webhook`	`PATCH /webhooks`	Change url/events in place, or `rotateSecret:true`. Prefer over delete+recreate
`delete_webhook`	`DELETE /webhooks`	Remove a registration

Share links

Tool	Maps to	Use
`create_share_link`	`POST /share`	Mint a public read-only link; `expiresInDays` for a TTL
`list_share_links`	`GET /share`	Audit every token minted, with an `active` flag
`revoke_share_link`	`DELETE /share`	Kill a leaked or stale link

Members and budget

Tool	Maps to	Use
`list_members`	`GET /members`	Humans and agent seats on a project
`add_agent_seat`	`POST /members`	Mint an agent seat; the `pb_` key is returned once (Team tier)
`invite_contributor`	`POST /members`	Passwordless guest invite, scoped to the projects you name (Team tier)
`revoke_member`	`DELETE /members`	Remove a seat; an agent's key dies with its last membership
`tier_status`	`GET /tier-status`	Your tier, API access, credit balance and limits — check before a large run
`submit_feedback`	`POST /feedback`	Tell the PB team what to improve: feature requests, friction, bugs, notes

Source, licence, registry

Source: https://github.com/moxzas/productbrain-mcp (MIT). Issues and pull requests welcome there.
npm: @productbrain-com/mcp. Every release is published from the repository's tag of the same version.
MCP registry name: io.github.moxzas/productbrain (server.json in this repo is the registry manifest).
The server sends User-Agent: productbrain-mcp/ so you can tell MCP traffic from raw REST calls in your own logs.

Proving it works

Two headless scripts in the repository (src/spike-proof.ts, src/parity-proof.ts; not shipped in the npm package), both run against a real deployment. Use a throwaway project on your own account:

PRODUCTBRAIN_API_KEY=pb_your_key \

PRODUCTBRAIN_PROJECT_ID=your-sandbox-project \ npm run spike # transport + auth + one read + one write

PRODUCTBRAIN_API_KEY=pb_your_key \ npm run parity # every non-plan tool once, on a throwaway project

parity creates its own throwaway project and cleans up after itself (archiving it at the end — there is no project-delete endpoint).

The Team-tier tools (add_agent_seat, invite_contributor) return 403 team_tier_required on a Builder key, and that counts as a pass — with one caveat worth knowing. It proves the shim reached the right route and passed the error and its _meta tip straight through; it does not validate the request body, because the tier gate runs before the body is read. Run parity with a Team-tier key to check those two properly.
