# graftfork > graftfork keeps a changed copy of an open-source project current with upstream releases. It moves your changes onto each new release, runs your tests in a sandbox, and keeps the moved branch only when every change lands and the tests pass. It can also rebuild a program blind from a written spec, kept only when every case passes. This is graftfork.ai, graftfork's front door for agents. https://graftfork.ai/mcp and https://graftfork.com/mcp are the same MCP server, and https://graftfork.ai/api/v1 and https://graftfork.com/api/v1 the same API: a token works at both. Sign-in, OAuth and the pages for people stay on graftfork.com. ## Connect - MCP server: https://graftfork.ai/mcp (Streamable HTTP). The same server as https://graftfork.com/mcp. - OAuth: a 401 from https://graftfork.ai/mcp names https://graftfork.ai/.well-known/oauth-protected-resource. The authorization server is https://graftfork.com: Dynamic Client Registration at https://graftfork.com/oauth/register (public clients, no secret), then the authorization code with PKCE S256. A person signs in and allows the client. - Bearer token: `Authorization: Bearer graft_...`, a personal API token a person makes at https://graftfork.com/app#settings. - Claude: https://claude.ai/directory/graftfork - Claude Code: `claude mcp add --transport http graftfork https://graftfork.ai/mcp` - Command line: `npm install -g graftfork` (Node 22.18 or newer), then `graft copies` with the token in GRAFT_TOKEN. - HTTP API: https://graftfork.ai/api/v1, described at https://graftfork.ai/api/v1/openapi.json - No token at all: `POST https://graftfork.ai/api/try` with `Content-Type: application/json` and `{"repo": "owner/name"}` tries a public fork. It never pushes and runs no agent. - No person at all: an agent with a wallet makes its own account with `POST https://graftfork.ai/api/v1/agents` (x402, 12 USD in USDC for 30 days of Premium). ## Tools A token sees the ones its scopes allow. - `track_change`: Track a repository with Graft (sync) - `list_copies`: List tracked copies (read) - `status`: Copy status (read) - `sync_now`: Sync now (sync) - `set_copy`: Set a copy's desired state (sync) - `take_move`: Take a delivered move (read) - `revert_move`: Revert a move (sync) - `send_upstream`: Send a change upstream (read) - `build_upstream`: Build a change for upstream (sync) - `upstream_status`: An upstream build (read) - `track_upstream_pr`: Track an upstream pull request (sync) - `explain_stop`: Why a sync stayed (read) - `list_pending_conflicts`: List waiting conflicts (read) - `get_conflict`: Get a conflict (read) - `submit_resolution`: Submit a resolved file (resolve) - `answer_question`: Answer a question (resolve) - `check_change`: Check a change (sync) - `check_status`: A change check's result (read) - `upgrade_dependency`: Upgrade a dependency (sync) - `get_upgrade`: An upgrade's result (read) - `regen_connect`: Connect a spec for rebuilds (sync) - `regen_run`: Rebuild a spec now (sync) - `regen_set`: Set a spec's desired state (sync) - `regen_disconnect`: Disconnect a spec (sync) - `regen_status`: Specs and rebuilds (read) - `regen_record`: A rebuild's signed record (read) - `regen_rejudge`: Judge a rebuild's builds again (sync) - `regen_report`: A spec's report (read) - `regen_report_refresh`: Grade a spec's record again (sync) - `regen_draft_check`: Check a branch's record (sync) - `regen_draft_rebuild`: Rebuild a branch's record (sync) - `regen_draft_status`: A spec's drafts (read) - `regen_order_create`: Start a change order (sync) - `regen_order_write`: Write a change order's files (sync) - `regen_order_check`: Check a change order (sync) - `regen_order_rebuild`: Rebuild from a change order (sync) - `regen_order_status`: A spec's change orders (read) - `regen_order_discard`: Discard a change order (sync) - `usage`: Plan and usage (read) - `webhook_add`: Add a webhook (sync) - `webhook_list`: Webhooks and deliveries (read) - `webhook_remove`: Remove a webhook (sync) - `webhook_test`: Test a webhook (sync) - `list_fork_alerts`: List fork watch alerts (read) - `path_policy`: Protected paths (read) - `org_settings`: An organization's settings (read) - `org_settings_set`: Change an organization's settings (admin) - `org_notify_set`: Mute organization email (sync) - `org_channels`: An organization's team channels (read) - `org_channel_add`: Add a team channel (admin) - `org_channel_set`: Change a team channel (admin) - `org_channel_remove`: Remove a team channel (admin) - `org_channel_test`: Send a test to a team channel (admin) - `org_audit_verify`: Check an organization's audit log (read) - `org_review_queue`: Review queue (read) ## Prices - Free: $0. 10 syncs a month, 5 copies, the first conflict resolved free once (up to $1.25 of agent work). - Premium: $12 a month. 40 syncs a month and $6 of agent work included, up to $1.25 a sync. Top-up: $10 adds $7. - Team: $15 per fork a month, 1 to 20 forks. - Machine-readable: https://graftfork.ai/pricing.json ## Limits that matter to an agent - Spend is quoted first. Give a run a ceiling with `max_usd`; if it could cost more, the answer is `price_quote` and nothing is spent. - Monthly caps. Agent work stops at the plan's included amount (no overage; it waits for the 1st, UTC) and at the token's own monthly cap, which the person sets (402 `token_budget_spent`). The `usage` tool shows what is left. - Rate: 120 requests a minute per token, 30 of them changes. - graftfork never pushes to your branches. By default it writes nothing to your repository: the moved branch, `graft/`, waits for you to take it. A pull request is opt-in per copy. - Nothing an agent sends moves a copy by itself. A resolution is stored, graftfork syncs again, and the tests decide. ## More - Every tool with its input schema, and every HTTP operation: https://graftfork.ai/llms-full.txt - OpenAPI: https://graftfork.ai/api/v1/openapi.json - MCP Server Card: https://graftfork.ai/mcp/server-card - API catalog: https://graftfork.ai/.well-known/api-catalog - For people: https://graftfork.com (try it, pricing, results, docs) - Support: support@graftfork.com, by email only.
