Athena Protocol MCP Server

An intelligent MCP server that acts as an AI tech lead for coding agents - providing expert validation, impact analysis, and strategic guidance before code changes are made. Like a senior engineer reviewing your approach, Athena Protocol helps AI agents catch critical issues early, validate assumptions against the actual codebase, and optimize their problem-solving strategies. The result: higher quality code, fewer…

People who work with code analysis, thinking validation and context engineering and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Athena Protocol

before you install - you'll need

Set ANTHROPIC_API_KEY, DEFAULT_LLM_PROVIDER before connecting.

Claude Code

claude mcp add n0zer0d4y-athena-protocol -- npx -y @n0zer0d4y/athena-protocol

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "n0zer0d4y-athena-protocol": {
      "command": "npx",
      "args": [
        "-y",
        "@n0zer0d4y/athena-protocol"
      ]
    }
  }
}

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

npm package @n0zer0d4y/athena-protocol - published under the repo owner's npm scope (@n0zer0d4y)

registry namespace io.github.n0zer0d4y is GitHub-verified and matches the repo owner

03 · What Athena Protocol can do

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

Limitations (from the README)

The persistent memory system (thinking-memory.json) is currently under review and pending refactoring. While functional, it: - Creates a memory file in the project root directory - Persists validation history across sessions - May require manual cleanup during testing/development

What is Athena Protocol?

Is Athena Protocol still maintained?

Yes - as of 2026-09-18, its last commit was 2026-01-04. We re-verify nightly.

How do I install Athena Protocol?

Run `npx -y @n0zer0d4y/athena-protocol`. The README documents 2 environment variables (ANTHROPIC_API_KEY, DEFAULT_LLM_PROVIDER) to set first. Set ANTHROPIC_API_KEY, DEFAULT_LLM_PROVIDER before connecting. You can also paste the ready-made client config above.

Does Athena Protocol 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.
