Codecanvas MCP Server

Understand an unfamiliar Python system before spending thousands of tokens reading it file by file. Its 13 documented tools cover flow, state. 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 Python.

01 · Install Codecanvas

Claude Code

claude mcp add donggyun112-codecanvas -- uvx codecanvas-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "donggyun112-codecanvas": {
      "command": "uvx",
      "args": [
        "codecanvas-mcp"
      ]
    }
  }
}

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

license MIT - declared in the repository

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

registry namespace io.github.donggyun112 is GitHub-verified and matches the repo owner

03 · What Codecanvas can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can inspect the active root, Python file count, cache, worker interpreter, and nested project candidates, get one compact, citation-ready view of a function's branches, outcomes, downstream calls, and effects, inspect a structured branch tree with subjects, conditions, scopes, and nesting, and get the enclosing guards for each return or raise, plus complexity and unreachable code.

06 · Codecanvas FAQ

Is Codecanvas still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-23. We re-verify nightly.

What can Codecanvas do?

With this server connected, an agent can inspect the active root, Python file count, cache, worker interpreter, and nested project candidates, get one compact, citation-ready view of a function's branches, outcomes, downstream calls, and effects, inspect a structured branch tree with subjects, conditions, scopes, and nesting, and get the enclosing guards for each return or raise, plus complexity and unreachable code.

How do I install Codecanvas?

Run `uvx codecanvas-mcp`. You can also paste the ready-made client config above.

Does Codecanvas 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.
