Redcon MCP Server

Deterministic context budgeting for AI coding agents Stop sending agents 200k tokens of irrelevant code. Redcon scores, compresses, and packs repo context so your agent gets what it actually needs. 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 Redcon

Claude Code

claude mcp add natiixnt-redcon -- uvx redcon

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "natiixnt-redcon": {
      "command": "uvx",
      "args": [
        "redcon"
      ]
    }
  }
}

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 no standard license detected - usage rights unclear; check the repo before commercial use

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

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