Sinter MCP Server

A local code knowledge graph for coding agents, shipped as one static binary. sinter builds a typed, directed graph of a repository's symbols with tree-sitter and keeps it fresh incrementally. Start in an unfamiliar repository with sinter map: it returns a bounded structural inventory with module node/file counts, dependency hubs measured by graph in-degree, documentation entry points, and graph-health limitations.…

People who work with code graph, codex and coding agents and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Sinter

Claude Code

claude mcp add shellfu-sinter -- uvx sinter-io

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "shellfu-sinter": {
      "command": "uvx",
      "args": [
        "sinter-io"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-08-15 - young repo, little track record yet

license Apache-2.0 - declared in the repository

pypi package sinter-io - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.shellfu is GitHub-verified and matches the repo owner
