Engram: Index

Get a structural overview of a codebase — no file reading needed. Uses the engram MCP (which supersedes the old codegraph MCP).

When to use

• "Understand this codebase"
• "What does this repo do?"
• "Give me an overview of this project"
• First encounter with a new repository

Workflow

1. Index the repo. Call scan_repo with the absolute path.

   scan_repo({ "path": "/absolute/path/to/repo" })
   

2. Get the architecture map. Call architecture — one call replaces the old repository_stats + central_symbols + bridge_symbols + call_communities.

   architecture({ "limit": 20 })
   

3. Get a context packet (optional). For a high-level narrative:

   get_context({ "focus": "main" })
   

How to synthesize

Present a concise narrative:

This codebase has N symbols across M modules. The core abstractions are X, Y, Z (top PageRank). Be careful with B — it's a bridge symbol.

Do NOT read individual files unless asked. The graph tells you the structure.

Tools

Tool	Purpose
scan_repo	Index the repo.
architecture	Central + bridges + communities + stats.
get_context	Fused context packet.
symbol_context	Deep-dive a symbol (follow-up).
