ask-me-mcp

A persona MCP server. Ask Claude / ChatGPT / Grok about the operator's work, patterns, availability, and offer — grounded in their public résumé, projects index, and offer page.

Reference implementation of the MCP-Server Harness pattern. This repo is a working example of the same architecture the operator sells as a productized 6-week engagement. If you like the shape, that's the sales pitch — see The pattern at the bottom.

What it does

Six typed tools any AI-assistant user can call:

Every response ships with a confidence label and a source citation. The server never invents; if the grounding data doesn't say it, the server doesn't say it.

Install (as a user)

The remote endpoint speaks MCP Streamable HTTP + OAuth 2.1. Three ways to connect:

1. Claude Desktop — connector directory ("Connect" button)

Add via the Claude Desktop UI: Settings → Connectors → Add custom connector → URL: https://ask-me-mcp-xi.vercel.app/api/mcp. Click Connect. The desktop client discovers OAuth metadata, registers as a client, exchanges tokens, and mounts the tools. No manual config.

2. Claude Desktop / Claude Code — config file (skip OAuth)

Add to claude_desktop_config.json — location varies by OS; see Claude Desktop config docs:

{
  "mcpServers": {
    "ask-me": {
      "url": "https://ask-me-mcp-xi.vercel.app/api/mcp"
    }
  }
}

3. Claude Code CLI

claude mcp add --scope user ask-me https://ask-me-mcp-xi.vercel.app/api/mcp

Local stdio (development)

For local stdio dev (no HTTP, no OAuth — auth doesn't apply to stdio):

{
  "mcpServers": {
    "ask-me": {
      "command": "node",
      "args": ["/absolute/path/to/ask-me-mcp/dist/src/server.js"]
    }
  }
}

Then in any Claude Code session:

what's Ilyes's current focus? what patterns has he shipped for LLM evaluation? is he available for a Playbook engagement in October?

Develop (as a maintainer)

Requirements

• Node.js 20+

• npm (or pnpm / yarn — package.json is npm-first)

Setup

git clone https://github.com/tounsils/ask-me-mcp.git
cd ask-me-mcp
npm install

Run locally as a stdio server

npm run dev

Point Claude Code or the MCP Inspector at the resulting process.

Build for production

npm run build

Outputs to dist/.

Deploy to Vercel

# Set the JWT signing secret (one-time; required for OAuth).
vercel env add MCP_JWT_SECRET production
# Paste a long random string. Generate one: `openssl rand -base64 48`.

vercel deploy --prod

The api/mcp.ts handler serves the Streamable HTTP transport with OAuth 2.1 protection — the format Claude's connector directory and ChatGPT's Apps SDK both use. See docs/oauth-flow.md for the full architecture.

Run the eval corpus

npm run eval           # 15 tool cases against handlers directly (no HTTP)
npm run eval:oauth     # 6-step end-to-end OAuth flow (needs MCP_JWT_SECRET)

The tool corpus fails the build if fewer than a threshold percentage of expected answers match. Pass or nothing ships.

The OAuth flow test exercises register → authorize → token → protected /api/mcp → 401 challenge → refresh — all in-process against Vercel-shaped mock req/res objects.

The pattern: the MCP-Server Harness

This project is a reference implementation of a pattern the operator ships to clients as a productized 6-week engagement — the MCP-Server Product Playbook.

The shape:

1. Typed tool contract. Six JSON-schema-strict tools. Nothing free-form. The model can only invoke these, only with these arguments.

2. Coordinator + specialists (extensible). v0 has one coordinator (the MCP server routing tool calls). v1 will add elicitation + supervisor agents inside more complex tools.

3. Typed signal vector. Structured facts extracted from the grounding data. Not free-text.

4. Versioned reasoning specification. The tool implementations ARE the reasoning spec — versioned in the code, not in a prompt.

5. Rails + confidence. Every response carries confidence + sources + optional disclaimers. The model can display them.

6. External grounding. The server queries src/grounding/data.json; the model never invents.

7. Evaluation corpus + eval runner + certification. eval/corpus.json has expected answers; npm run eval replays them. Ships or doesn't.

If you're building a product that fits this shape (career guidance, medical triage, legal intake, financial planning, coaching, expert-system anything), the operator sells a 6-week fixed-scope engagement to ship it. See get_offer_details or email tounsils@gmail.com.
