“Is there a signed, primary-source count of the MCP ecosystem?”

Tell an agent

Show the latest State of MCP census.

Get the signed count of MCP servers in the official registry.

GET /v1/state-of-mcp/trend Get State of MCP growth over time · V1 State Of Mcp Trend #

Ask an LLM

“How has the number of MCP servers grown over recent weeks?”

“Is the share of remote and keyless MCP servers rising?”

Tell an agent

Show the State of MCP trend for the last {days} days.

Get the daily State of MCP growth series.

GET /v1/facts Get a verified fact via GET · V1 Facts #

Ask an LLM

“Can I get any tool's value as a canonical fact with an honest verification block?”

“What is the difference between a signed fact and a verified one?”

Tell an agent

Fetch the bitcoin price as a canonical fact using the GET facts endpoint.

Get a verified-fact record for current weather with a simple GET.

POST /v1/facts Request a verified fact via POST · V1 Facts #

Ask an LLM

GET /v1/answer Get a signed answer with receipts via GET · V1 Answer #

Ask an LLM

“Can I ask a factual question and get a signed answer with its full evidence chain?”

“How is confidence computed in an answer with receipts?”

Tell an agent

Get a signed answer with receipts for my question using GET.

POST /v1/answer Submit premises for a signed answer via POST · V1 Answer #

Ask an LLM

“Can I post structured premises and get per-premise verdicts in one signed answer?”
