angr-api-mcp

MCP server for angr binary analysis API workflow retrieval.

Extracts real API usage patterns from angr's source code and angr-doc examples, then indexes them with semantic search so LLMs can query correct API call sequences.

Installation

Via Claude Code (recommended)

claude mcp add angr-api-mcp -- uvx angr-api-mcp

Via Claude Desktop

{
  "mcpServers": {
    "angr": {
      "command": "uvx",
      "args": ["angr-api-mcp"]
    }
  }
}

Via pip

pip install angr-api-mcp

Related MCP server: Satori

First-time setup

After adding the server, build the index by calling the initialize_index tool from Claude:

initialize_index()

This clones angr and angr-doc from GitHub and builds the semantic index (~5–10 minutes). The index is stored at ~/.local/share/angr-api-mcp/chroma_db and persists across restarts.

Or run from the command line:

angr-api-mcp-admin build-index

# Point at local repos to skip cloning
angr-api-mcp-admin build-index --angr-path /path/to/angr --angr-doc-path /path/to/angr-doc
