mcp-wiki-server

by AustinAbhari

mcp-wiki-server

A minimal, agent-agnostic MCP server that exposes search over local markdown documentation. Any MCP-compatible client (Claude Code, Claude Desktop, or a custom agent built on any model) can connect to it — the server has no knowledge of which agent or LLM is calling it.

Tools exposed

  • search_docs(query, limit?) — keyword search across docs/*.md, returns matching files with a snippet.

  • read_doc(path) — read the full contents of a doc by its relative path.

Setup

npm install
npm run build

Run it standalone (for debugging)

npm run inspect

This launches the MCP Inspector, a web UI for calling your tools directly without needing a full LLM client.

Wire it into Claude Code

claude mcp add wiki-search -- node /absolute/path/to/mcp-wiki-server/dist/index.js

Wire it into Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "wiki-search": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-wiki-server/dist/index.js"]
    }
  }
}

Any other MCP client follows the same pattern: point it at node dist/index.js as a subprocess command.

Add your own docs

Drop .md files into docs/ (subfolders supported). No re-deploy needed — search_docs reads from disk on every call.

Next steps toward a shared/remote deployment

  1. Swap StdioServerTransport for the Streamable HTTP transport in src/index.ts.

  2. Point docs/ at a real source (Confluence/Notion/Drive) instead of local files.

  3. Containerize and deploy to Cloud Run.

  4. Add auth (OAuth2/OIDC or Cloud Run IAM) in front of the HTTP endpoint.

Available Tools

Inputs: path (required).

    A3.9/5.0

    Scored across 2 tools

    Disambiguation5/5

    The two tools serve clearly distinct purposes: search_docs finds documents by keyword, while read_doc retrieves the full content of a known document by path. There is no overlap or ambiguity between them.

    Naming Consistency4/5

    Both tools use a verb_noun pattern (search_docs, read_doc), making the pattern predictable. There is a minor inconsistency in pluralization—search_docs is plural while read_doc is singular—but it does not cause confusion.

    Tool Count3/5

    With only two tools, the server feels minimally scoped. This is appropriate for a simple read-only wiki, but it is on the thin side and offers no additional utility beyond search and read.

    Completeness4/5

    For a read-only documentation server, the search-and-read lifecycle is complete. The only notable gap is the lack of a way to list or browse all documents without a search query, which could be a minor workaround in some cases.
