MCP 服务器

TempoGraph

Code graph context engine that parses codebases with tree-sitter (170+ languages), builds structural dependency graphs, and provides 24 MCP tools for code intelligence. One prepare_context call gives your AI agent the right files for any task. Includes focus, blast radius, hotspots, dead code detection, and hybrid search.

README

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.

Model	Without TempoGraph	With TempoGraph	Improvement
GPT-4o	21.7% F1	27.5% F1	+27%
GPT-4o-mini	19.2% F1	24.5% F1	+28%
qwen2.5-coder:32b	—	—	+18.6% (p=0.049)

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:

Tool	When to use it
`blast_radius`	"What breaks if I change this file?"
`focus`	"Show me everything related to auth"
`hotspots`	"Which files are riskiest to change?"
`dead_code`	"What can I safely delete?"
`diff_context`	"What's the impact of my current changes?"
`overview`	"Orient me in this new codebase"

<details> <summary>All 24 tools</summary>

Tool	What it does
`prepare_context`	One-shot context for a task — the primary tool
`overview`	Repository orientation: size, languages, entry points
`focus`	Connected subgraph around a symbol — callers, callees
`blast_radius`	What breaks if you change this file or symbol
`diff_context`	Impact analysis of changed files
`hotspots`	Ranked risk list — complexity x coupling x size
`dead_code`	Unreferenced symbols — cleanup candidates
`lookup`	"Where is X?", "What calls X?"
`dependencies`	Circular imports, dependency layers
`architecture`	Module-level dependency view
`symbols`	Full symbol inventory
`file_map`	File tree with top symbols per file
`search_semantic`	Hybrid keyword + vector + structural search
`cochange_context`	Files that historically change together
`suggest_next`	Predicts the next useful tool call
`run_kit`	Composable multi-tool workflows
`stats`	Token budget estimates
`get_patterns`	Codebase conventions and idioms
`report_feedback`	Log whether output was useful
`learn_recommendation`	Suggestions from feedback history
`index_repo`	Build or rebuild the graph
`watch_repo` / `unwatch_repo`	Live incremental updates
`embed_repo`	Generate vector embeddings

</details>

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.
