It exposes grammar specifications, documentation, code examples, compiler tools, and prompt templates through a standardized protocol -- so any MCP-compatible AI client can write, validate, format, and debug Jac code.\n\n## Installation\n\n`jac-mcp` is a plugin that runs on top of the `jac` binary, which provides the jaclang runtime. Install the binary first (see the [installation guide](https://docs.jaseci.org/quick-guide/install/)), then add the plugin:\n\n```bash\njac install jac-mcp\n```\n\n> `jaclang` is provided by the `jac` binary at runtime (a host dependency); it is not pulled from PyPI.\n\n## Quick Start\n\nStart the MCP server with the default **stdio** transport, ready for IDE integration:\n\n```bash\njac mcp\n```\n\nInspect the available resources, tools, and prompts:\n\n```bash\njac mcp --inspect\n```\n\nThen add the server to your AI client's MCP configuration. A minimal entry looks like:\n\n```json\n{\n  \"mcpServers\": {\n    \"jac\": {\n      \"command\": \"jac\",\n      \"args\": [\"mcp\"]\n    }\n  }\n}\n```\n\nSee the [MCP reference](https://docs.jaseci.org/reference/mcp/) for the full list of tools, resources, prompts, transport options, and per-IDE integration steps.\n\n## Documentation\n\n- **Agent Skills & MCP guide**: [https://docs.jaseci.org/quick-guide/agent-skills-and-mcp/](https://docs.jaseci.org/quick-guide/agent-skills-and-mcp/)\n- **MCP reference**: [https://docs.jaseci.org/reference/mcp/](https://docs.jaseci.org/reference/mcp/)\n- **Jac language**: [https://www.jac-lang.o…","publisher":null,"homepage":"https://jac-lang.org","repository":"https://github.com/jaseci-labs/jaseci/blob/main/docs/docs/community/release_notes/jac-mcp.md","version":"0.1.24","license":null,"protocols":["mcp"],"tags":["jac","jaclang","jaseci","mcp","ai","model-context-protocol"],"pricing":null,"endpoints":[{"url":"pypi:jac-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"ai.prompting","name":"Prompt Management","confidence":1,"provenance":"derived"},{"slug":"dev.docs-lookup","name":"Documentation Lookup","confidence":0.791,"provenance":"derived"}],"categories":["ai","dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"jac-mcp","registry":"pypi","observedAt":"2026-09-15T21:22:09.016Z","publishedAt":"2026-06-25T11:04:07.774881Z","latestVersion":"0.1.24"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"jac-mcp","url":"https://pypi.org/project/jac-mcp/","firstSeenAt":"2026-09-09T22:22:12.608Z","fetchedAt":"2026-09-15T21:20:33.691Z","normalizedAt":"2026-09-15T21:20:33.691Z"}]},"firstSeenAt":"2026-09-09T22:22:12.608Z","updatedAt":"2026-09-15T21:22:09.016Z"}
