TempoGraph MCP Server

TempoGraph

Your AI agent finds the right files. Every time.

TempoGraph builds a dependency graph of your codebase and gives your AI coding agent exactly the files it needs before making changes. One tool call. No guessing.

The Problem

AI coding agents guess which files to look at. They search by filename, grep for keywords, and hope for the best. In large codebases, they miss critical dependencies, break things downstream, and waste tokens reading irrelevant code.

The Fix

pip install tempograph

Add to your MCP config (Claude Code, Cursor, Windsurf, or any MCP client):

{
  "mcpServers": {
    "tempograph": {
      "command": "tempograph-server",
      "args": []
    }
  }
}

Your agent calls prepare_context with a task description. TempoGraph returns the exact files that matter — based on real dependency analysis, not text matching.

Does It Work?

Tested on real PRs from django, flask, httpx, fastapi, requests, and pydantic. Task: predict which files need to change.

Consistent improvement across every model. 2-3x more tasks helped than hurt. No other code context tool publishes retrieval benchmarks with statistical significance.

How It Works

your repo ──→ tree-sitter parse ──→ symbols + edges ──→ SQLite graph
                                                            │
                    AI agent calls prepare_context ─────────┘
                                                            │
                              ◄── KEY FILES + callers + callees + risk signals

• Parses your code with tree-sitter into a structural dependency graph
• Content-hashed and stored in SQLite — only changed files get re-parsed
• Warm queries in ~21ms. Branch switching doesn't trigger a rebuild
• Knows when NOT to inject context (adaptive gating avoids harming diffuse commits)

What Else Can It Do?

Beyond prepare_context, TempoGraph exposes 24 MCP tools for deeper analysis when your agent needs it:

CLI

# Orient in a new repo
tempograph ./my-project --mode overview

# What's connected to auth?
tempograph ./my-project --mode focus --query "authentication"

# What breaks if I touch db.ts?
tempograph ./my-project --mode blast --file src/lib/db.ts

# Find dead code to clean up
tempograph ./my-project --mode dead

Python API

from tempograph import build_graph

graph = build_graph("./my-project")
results = graph.search_symbols("handleLogin")
importers = graph.importers_of("src/lib/db.ts")
dead = graph.find_dead_code()

Languages

Python, TypeScript, JavaScript, Rust, Go, Java, C#, and Ruby get deep extraction (custom tree-sitter handlers). 170+ additional languages are supported via generic handler. pip install tempograph[full] for everything.
