**Hybrid search + code graph + semantic memory in a single local MCP server — under 350 MB RAM.**

Nexus-MCP is a code intelligence server for the [Model Context Protocol](https://modelcontextprotocol.io). It gives AI agents precise, token-efficient answers about your codebase without cloud dependencies: no API keys, no data egress, no subscriptions.

```
pip install nexus-mcp-ci
claude mcp add nexus-mcp-ci -- nexus-mcp-ci
```

## The Problem It Solves

AI coding agents are token-inefficient by default. An agent trying to understand `verify_credentials()` typically:

1. `Glob("src/**/*.py")` → 120 files returned, agent reads the most likely 8 → **~12,000 tokens**
2. `Grep("verify_credentials")` → 3 matches, agent reads surrounding context → **~4,000 tokens**
3. `Read("auth/middleware.py")` → full 400-line file to understand callers → **~3,000 tokens**

**Total: ~19,000 tokens, 3+ tool calls, no graph relationships.**

With Nexus-MCP:

1. `explain("verify_credentials")` → symbol definition + all callers + all callees + complexity metrics → **~1,500 tokens, 1 tool call**

Or for discovery:

1. `search("credential verification flow")` → top-10 semantically relevant chunks across the codebase → **~2,000 tokens, 1 tool call**

**Estimated savings: 30–60% token reduction per coding session.** The exact numbers depend on codebase size and task type — see the [benchmarks table](#token-efficiency) below.
