Sonde MCP Server

A local code-context engine for AI coding agents. Sonde indexes a TypeScript, Python, or Swift repository into a symbol-level graph in SQLite and exposes three MCP tools - find_symbols, query_graph, and get_impact_radius - so an agent can answer who calls this, what breaks if I change it, and which tests relate to it in one call instead of a search loop.

People who work with code analysis, developer tools and swift and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Sonde

Claude Code

claude mcp add anishmoncivarghese-sonde -- npx -y @cheppulabs/sonde

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "anishmoncivarghese-sonde": {
      "command": "npx",
      "args": [
        "-y",
        "@cheppulabs/sonde"
      ]
    }
  }
}

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 2026-08-24 - young repo, little track record yet

license Apache-2.0 - declared in the repository

npm package @cheppulabs/sonde - the @cheppulabs scope differs from the repo owner (anishmoncivarghese); confirm it's the project's official package

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

06 · Sonde FAQ

What is Sonde?

A local code-context engine for AI coding agents. Sonde indexes a TypeScript, Python, or Swift repository into a symbol-level graph in SQLite and exposes three MCP tools - find_symbols, query_graph, and get_impact_radius - so an agent can answer who calls this, what breaks if I change it, and which tests relate to it in one call instead of a search loop.

Is Sonde still maintained?

Yes - as of 2026-09-18, its last commit was 2026-08-31 and it shipped 9 releases in the last 90 days. We re-verify nightly.

How do I install Sonde?

Run `npx -y @cheppulabs/sonde`. You can also paste the ready-made client config above.

Does Sonde run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
