@wiki0/mcp

MCP server for wiki0: search a project's docs and get the right section with a path:start-end citation.

Install

pnpm add -g @wiki0/mcp

The package exposes the wiki0-mcp binary.

Tools

| Tool | Purpose | | ---------------- | -------------------------------------------------------------- | | search_docs | One cited section per document, authoritative docs first | | show_section | Text of a citation, path:line, path#heading, path or title | | get_context | Search plus the top sections as cited Markdown | | index_docs | Index the project docs | | index_status | Index path and staleness | | lint_docs | Broken links and anchors with path:line | | check_docs | After editing docs: problems in the changed files | | link_graph | Documents and links | | list_documents | Outline, status, type and link counts per document | | backlinks | Documents linking to a document | | wiki0_info | Version and safety settings |

Tools return JSON as both text and structured content; failures return isError: true.

To show the user this project's docs, run npx @wiki0/cli ui; it prints the URL and returns, and a second run reuses the open server.

Roots and safety

Each tool takes an optional root. The server only allows roots under its working directory unless WIKI0_ALLOWED_ROOTS lists others (comma-separated). WIKI0_READ_ONLY=true blocks index_docs and check_docs, the only tools that write (to the index, never to your files).

The index lives in ~/.cache/wiki0/<project>/index.db. Set WIKI0_INDEX so the CLI and the server use the same file if their environments differ.
