wikijs-mcp: Instructions file for Claude Code

CLAUDE.md

wikijs-mcp CLAUDE.md is an instructions file for Claude Code from cahaseler/wikijs-mcp. It costs 684 tokens per session, scanned A, original, from a forked repository, MIT.

Development instructions for wikijs-mcp, an MCP server that connects AI assistants to WikiJS, a platform for managing wiki content. They document setup, build, development, testing, and the server's three-layer structure.

In plain words
What is it for?
Use them when building, testing, cleaning, running, or understanding the WikiJS MCP server.
Why use it?
They give an agent the repository-specific commands and architecture needed to change or run the project correctly.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is cahaseler/wikijs-mcp's own configuration. It tells Claude Code how to work on wikijs-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything wikijs-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wikijs-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Commands

Build Commands

  • npm run build - Compiles TypeScript to JavaScript and sets executable permissions
  • make build - Alternative build command using Makefile
  • npm run codegen - Generates TypeScript types from WikiJS GraphQL schema (requires WIKIJS_URL in .env)

Development Commands

  • make run - Builds and runs the MCP server
  • make clean - Removes build artifacts
  • docker-compose up -d - Starts a local WikiJS instance for testing
  • docker-compose down - Stops the local WikiJS instance

Architecture

This is a Model Context Protocol (MCP) server that bridges AI assistants with WikiJS instances. The architecture follows a three-layer pattern:

Core Components

  1. MCP Layer (src/mcp/)

    • WikiJSMcpServer class manages the MCP server lifecycle and tool registration
    • Tools are registered in src/mcp/index.ts:27-54 with specific parameter schemas
    • Each tool is a separate module in src/mcp/tools/

  2. WikiJS Client Layer (src/wikijs/)

    • WikiJSClient class wraps GraphQL operations
    • Uses generated GraphQL types from src/wikijs/generated/graphql.ts
    • GraphQL queries are defined in src/wikijs/queries/pages.graphql

  3. Entry Point (src/index.ts)

    • Initializes WikiJS client with URL and API key from environment
    • Creates MCP server instance and connects via stdio transport
    • Handles fatal errors and process exit

Tool Architecture

Each MCP tool follows a consistent pattern:

  • Exports a createTool function that returns a handler
  • Exports a PARAMETERS schema for validation
  • Uses Zod for runtime parameter validation
  • Returns structured responses with content arrays

GraphQL Integration

The project uses GraphQL Code Generator to create typed SDK from WikiJS API:

  • Schema is fetched from ${WIKIJS_URL}/graphql
  • Queries in .graphql files generate TypeScript types
  • SDK provides type-safe methods for WikiJS operations

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
