Topos MCP Server
the agent harness for structural code quality Topos measures complexity, coupling, risky data flows, and agent cognitive load, then gives your agent a concrete target from SLOP to PLATINUM. It runs locally over stdio via the published package.
People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Topos
Claude Code
claude mcp add krv-labs-topos -- uvx topos-mcp Claude Desktop / Cursor / VS Code - add to config
{
"mcpServers": {
"krv-labs-topos": {
"command": "uvx",
"args": [
"topos-mcp"
]
}
}
} Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

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
license BSD-3-Clause - declared in the repository
pypi package topos-mcp - check the name against the project README before installing (PyPI has no namespace ownership)
registry namespace io.github.Krv-Labs is GitHub-verified and matches the repo owner

06 · Topos FAQ
What is Topos?
the agent harness for structural code quality Topos measures complexity, coupling, risky data flows, and agent cognitive load, then gives your agent a concrete target from SLOP to PLATINUM. It runs locally over stdio via the published package.
Is Topos still maintained?
Yes - as of 2026-08-25, its last commit was 2026-08-24 and it shipped 10+ releases in the last 90 days. We re-verify nightly.
How do I install Topos?
Run `uvx topos-mcp`. You can also paste the ready-made client config above.
Does Topos run locally?
Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
