Details
From the project READMENL;NL Labs MCP connector
Source for the read-only MCP server at https://mcp.nlnllabs.com/mcp. It reads the daily AI test results published on
nlnllabs.com and returns them to Claude, ChatGPT or any MCP client. No account or sign-in.
Tools:
list_jobs: the nine jobs, the models and systems tested on each, and the dates covered.get_pick: the outside model a job's page currently picks, with its date and figures. NL;NL Labs' own models are never the pick.get_model_history: one model's published results on one job, day by day.get_day_results: every model's result on one job on one day.
All data is read live from the public files on nlnllabs.com; nothing is stored here. Each tool call records the tool, the job, model or date asked about, the calling app's name and the time; not the question or the IP address. Records are deleted after 12 months.

Runs on Cloudflare Workers (wrangler.jsonc). Registry entry: com.nlnllabs/results (server.json).

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
