NerdyChefs Prompts

nerdychefs-mcp

An MCP server that gives your assistant access to the free prompt library at NerdyChefs.ai. Search for a task, open a pack, or pick a random prompt to try.

It runs over stdio and fetches prompts when you first need them. Data stays in memory for 60 minutes. Requires Node 20 or newer.

Tools

Category, persona, and tag filters use case-insensitive exact matches. Pack queries search titles and descriptions. Persona and tag queries match part of a name. Search results omit prompt text unless requested. Every argument above also carries its own description in the tool schema, so your client can show you the same detail inline.

Two things catch people out, and both fail quietly rather than with an error:

• Filter on the category NAME, not its id. list_categories returns both, and only Engineering & DevOps matches. The slug form engineering-devops returns an empty result.
• get_prompt ids are positions in the published prompt file, not ids from the website. Use an id from search_prompts, random_prompt or get_pack in the same session. An id copied from a nerdychefs.ai page, or saved from last week, can name a different prompt.

The resource nerdychefs://pack/{slug} returns the same JSON as get_pack with prompt summaries and no prompt text.

Configuration

NERDYCHEFS_API_BASE defaults to https://www.nerdychefs.ai/api. Set it in the server's environment to change the API path. Remote URLs must use HTTPS on www.nerdychefs.ai. Local HTTP addresses are accepted for fixture tests. Redirects are refused.

Files load on demand and are cached separately for 60 minutes. Failed requests get one retry. A failed tool call names the file that could not load.

Privacy

The only remote host the server talks to is www.nerdychefs.ai. It downloads public JSON files. Searches and filters run locally. No user queries, prompt inputs, or client conversations are sent to the site.

Nothing is logged or sent anywhere else. There is no telemetry, analytics, or runtime disk cache. Local fixture tests use a loopback HTTP server. Returned website links include the fixed utm_source=mcp, utm_medium=tool, and utm_campaign=nerdychefs_mcp parameters.

Attribution

Prompts from NerdyChefs.ai. Prompts are served live from nerdychefs.ai and remain that site's content. Each prompt result includes attribution and links to its prompt and pack pages. The package does not include the prompt corpus.

Development

pnpm installpnpm buildpnpm testNERDYCHEFS_LIVE=1 pnpm test

The regular tests use small local fixtures. The live smoke test runs only when NERDYCHEFS_LIVE=1. Start the compiled server with node dist/index.js, or use pnpm dev while editing. Standard output is reserved for MCP messages.
