    How to connect

    How to connect SpecPilot to Claude

    The server address to paste into Claude settings:

    https://init.specpilot.dev/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect SpecPilot to ChatGPT

    The server address to paste into ChatGPT settings:

    https://init.specpilot.dev/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).

    Server tool list (2)

    Raw names from tools/list. Only developers need these.

    specpilot_next_questionsReturns the still-unanswered SpecPilot onboarding questions of the next incomplete step, gated by the answers supplied so far - questions that do not apply to this kind of project are omitted, and options are filtered, badged or flagged the same way the SpecPilot web chat would. Stateless: send every answer collected so far on each call. Procedure: (1) Decide whether the repository already has real source code and set `isNewBuild` accordingly - it changes which onboarding analysis is generated at the end. (2) Infer what the repo already answers rather than asking: `platforms` from the dependency manifests and layout, `languageOverride`, `ideAgent` (you are the IDE - claudecode, cursor, copilot, codex, windsurf), `handle` from git config or the origin remote, `projectName` from the package manifest or folder name, and `projectDescription` from the README only if it plainly says what the project is. (3) Call this tool with what you have; answer what the repo makes obvious and ask the developer the rest, a whole step per message. Send an empty value for an optional question the developer declines, or it will be asked again; send `todoSentinel` verbatim when they do not know yet. For `projectDescription`, sending one of the returned chip labels exactly is what infers `projectCategory` and gates every later question - free prose infers nothing. Confirm any pre-seeded value rather than accepting it silently. (4) Loop until `done` is true, then call specpilot_generate_specs and follow its `nextSteps` for where each file goes.
    specpilot_generate_specsGenerates the complete SpecPilot .specs/ file set plus the matching IDE rules and slash-command files from a full answer set - identical to what the SpecPilot web chat produces for the same answers. Requires projectName and projectDescription. Returns the files to write and the steps to follow after writing them.
