README

contextflow-mcp

MCP server for Contextflow — semantic code search and AI-powered Q&A over vectorized repositories, directly inside Claude.

🚀 What is this?

contextflow-mcp is a Model Context Protocol server that connects Claude to a Contextflow snapshot — a vectorized index of your codebase. Once connected, Claude can:

🔍 Semantically search your code
💬 Answer natural language questions grounded in actual source code
📦 Inspect snapshot metadata (files indexed, status, branch)

🛠️ Tools exposed

Tool	Description
`get_context_info`	Returns metadata about the snapshot: name, branch, status, files and chunks indexed
`search_context`	Semantic search — returns the most relevant code chunks with file paths and line numbers
`ask_context`	AI Q&A — asks a question and gets an answer grounded in real source code

⚙️ Setup

1. Install dependencies

npm install

2. Build

npm run build

3. Configure Claude

Add the following to your Claude MCP config (claude_desktop_config.json or equivalent):

{
  "mcpServers": {
    "contextflow": {
      "command": "node",
      "args": ["/absolute/path/to/dist/index.js"],
      "env": {
        "CONTEXTFLOW_TOKEN": "YOUR_SNAPSHOT_PUBLIC_TOKEN",
        "CONTEXTFLOW_API_URL": "http://localhost:3001"
      }
    }
  }
}

See claude-config-example.json for a ready-to-copy template.

Variable	Required	Default	Description
`CONTEXTFLOW_TOKEN`	✅ Yes	—	Public token of the Contextflow snapshot
`CONTEXTFLOW_API_URL`	No	`http://localhost:3001`	Base URL of the Contextflow API
