MCP governance server in Go for the Agentic Wiki — knowledge that composes, not that you query
MCP governance server in Go for the Agentic Wiki — knowledge that composes, not that you query.
[!WARNING] Beta software. Cartographer is pre-1.0: the MCP tool surface, CLI and configuration may change between minor releases without a deprecation period. Breaking changes bump the minor version (0.x semantics) and are called out in the changelog. Expect rough edges — bug reports are very welcome.
LLM agents forget everything between sessions, and stateless RAG only bolts retrieval onto that amnesia. The alternative is a knowledge base the agent itself builds and maintains over time — but letting an agent loose on a folder of files ends in broken links, lost history, and silent corruption. Cartographer is the governance layer that makes the pattern safe: the agent works the wiki exclusively through MCP tools, and the server enforces every invariant — validation, linking, immutability gates, one git commit per write.
Cartographer implements the Agentic Wiki: a persistent knowledge base of interlinked Markdown files that an LLM agent grows and curates by talking to the server over the MCP protocol. The agent never touches the files directly.
The wiki is grounded in Karpathy's "LLM Wiki" pattern (operating model: knowledge accretes over time, it is not stateless RAG) on top of the OKF substrate (Open Knowledge Format v0.1 by Google Cloud) — each KB is a folder of .md files with YAML frontmatter, self-contained and version-controlled with git. Zero lock-in: the wiki is readable by any tool, including Obsidian and any text editor.
