Flat list of every probed endpoint, sorted by score.

GET

/providers

Provider catalog (publicnode, ankr, drpc, brave, official, …) with endpoint and chain counts.

/resolve?chainId=&slug=&rpc=&explorer=

Generic resolver. Pass any one identifier and get back the canonical chain record.

MCP: the decision layer for RPC selection

The MCP server at https://mcp.rpcscan.com exposes the same ranking engine that powers rpcscan.xyz wallet routing, so every tool call returns a decision derived from live probe telemetry, not a static record. Tools: rpcscan.fastest, rpcscan.report, rpcscan.compare, rpcscan.pq, rpcscan.providers, rpcscan.search.

Full MCP page → (decision logic, tool semantics, determinism classes, trust + failure model, agent-style examples).

Status

See /health for live probe-pipeline status, queue depth, and last-flush timestamp.
