    How to connect

    How to connect Bowmark to Claude

    The server address to paste into Claude settings:

    https://api.bowmark.ai/mcp/registry

    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 Bowmark to ChatGPT

    The server address to paste into ChatGPT settings:

    https://api.bowmark.ai/mcp/registry

    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.

    get_library**Use this whenever a task touches a live website.** It answers, definitively and cheaply, whether Bowmark can already DO the thing: look up current prices, check real availability or stock, search a site, get a quote or a fare, drive a configurator, start a booking, or pull anything that only exists behind a form, a filter, or a login. **Use this for Bowmark questions too.** Before answering how to write or run a Bowmark script, what the sandbox supports, or how to start when no site or task is named, call it with the caller's words. The matching entry gives the platform guidance; guessing from general programming knowledge does not. **Checking is cheap, so check.** One read-only call, no site is touched, and an unrecognized query returns a one-line index instead of an error, so the check never dead-ends and never costs you an attempt. If nothing fits, you have lost one cheap call and can use your normal approach. What comes back is the callable **function library** you write against: the runtime globals (`log`) PLUS, for each capability your query named, its namespace, TypeScript types, functions, and worked examples. Everything listed is real and callable. The language rules and how to run a script are on the `run` tool description. Pass `query` — what you want to DO (`"flights"`, `"price a GPU"`) or, if you have one in mind, the COMPANY or site (`"Kayak"`, `"newegg.com"`). If the caller gave only a URL, use its hostname as the query — the query parameters identify a page state, not the company. A phrase in the user's own words is fine; it is matched against the whole library. **You get what you asked about and nothing else.** If nothing matches — or you send no query — you get instead a one-line index: pick whichever entry fits and CALL AGAIN with its name to get the types and examples you need to write a script. **Every response is bounded, and it says so when it is a slice.** A broad query can match more than one response carries; when that happens the an
    run**Executes the task on the real websites** (the search, the price check, the availability lookup, the configurator, the booking flow) and returns what came back. Runs a script you authored against the `get_library` vocabulary, on the live sites, and returns `{ ok, result, logs, error, ms }`. Call `get_library` FIRST — it gives the exact function names, argument shapes, and return types; this description is the LANGUAGE + how-to (get_library is just the vocabulary). THE LANGUAGE — plain async JavaScript: • `bowmark` is a ready global (no import). Call capabilities off it — `await bowmark.<capability>.<method>(...)` — always `await`, they're async. • Individual sites are callable too, at `await bowmark.providers.<provider>.<fn>(...)`. Use one when you specifically want THAT site; otherwise prefer the capability, which fans out across sites and routes around failures. • Real control flow: `await`, `if`, loops, array methods (`map`/`filter`/`sort`/`slice`), and `Promise.all` for fan-out. • `return` a value to get it back (JSON-serialized). `log(...)` for progress lines. • Standard JavaScript built-ins are there (`JSON`, `Math`, `Date`, `RegExp`, `Intl`, `Promise`), plus `URL` and `URLSearchParams` — use them to resolve a relative link against the page it came from and to build query strings. Nothing else from the Web platform exists: no `fetch`, `setTimeout`, `TextEncoder` or `crypto`. • `bowmark` is the ONLY I/O — no `fetch`, `process`, filesystem, or `import`/`require`. Write a plain async body, not a wrapping function. • Keep scripts small and deterministic — no infinite loops. Runs in a hard sandbox with CPU + memory + wall-clock limits. **Your own tool-call budget is tighter than you'd guess, and it decides how many calls fit in one script.** Most MCP clients time a single tool call out at around 55 seconds, and ONE ordinary capability call already spends 30-55 seconds of that fanning out to live sites — see COMPOSITION below before calling a second capability in
    reportRecord what was missing, wrong, or incomplete so Bowmark can build it. Pass the `runId` returned by `run` when this report is about a run; omit it when `get_library` did not cover the task. This records feedback only and does not retry a run.
    list_secretsList the stored credentials this account holds, by NAME. Returns name, type, which hosts each may be used against, when it expires and when it was last used — never a value, and no Bowmark endpoint returns one. **Call this BEFORE `request_secret`.** A secret the user has already set is ready to use; asking for it again sends them to a page for nothing. In a script, refer to one by name: `bowmark.secret('acme_pw')`.
    request_secretCreate a named, empty slot for a credential and get back a link the user opens to fill it in. They type the value on a Bowmark page and choose how long it lives, from 5 minutes to never. It is encrypted in their own browser before it leaves, so nothing on the way — this connection included — ever sees it. **Give the user the link. Never ask them to type a password, API key or one-time code to you.** A credential in this conversation is in your context, in the transcript and in the logs. **Name it for the person, not for your script.** The name you pass is the heading on the page they open and the row they see in their credential list months later, so make it `<site>_<what it is>`: `letterboxd_password`, `stripe_api_key`, `acme_totp_seed`. A run id, a timestamp, a uuid or a bare `password` is refused. Call `list_secrets` first: if the name already exists and is set, use it instead. `name` is lowercase letters, digits, `_`, `.` and `-`. `hosts` narrows where the value may be used and is worth passing — a secret is refused against any other site.
    get_secret_linkReturn the dashboard link for one stored credential this account holds, so you can answer "where is my Acme password?" with somewhere to go. **It returns a URL, never a value** — opening it requires the user to be signed in and to confirm who they are, and only their own browser can read what comes back.
    list_connectionsList the saved logins this account holds — which site, which account, whether it is still good, and when it was last used. A live one means a script can reach that site's signed-in pages with no sign-in step and usually no browser. Useful before a task that needs an account: a connection marked `needs_reauth` or `expired` is why a run would pause and ask the user to sign in again. Revoking one is deliberately not a tool — it is the user's to do, at https://bowmark.ai/dashboard/connections.
