Overview

Maintained by StarkWare inside the starknet-specs repo, this MCP server exposes all Starknet JSON-RPC v0.10.2 methods as agent-callable tools: reading blocks, transactions, contract state and storage, tracing and simulating transactions, calling contracts, estimating fees, and switching RPC endpoints mid-session. A builder plugs it into an MCP client to give an agent direct Starknet node access for debugging or exploring on-chain behavior without writing raw RPC calls.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — as documented by the project, not run by us

Runtime: Python (server script in starkware-libs/starknet-specs, mcp/server.py)

claude mcp add --env STARKNET_RPC_URL=<your-rpc-url> starknet -- python mcp/server.py
claude mcp add --scope user --env STARKNET_RPC_URL=<your-rpc-url> starknet -- python /absolute/path/to/mcp/server.py
python mcp/server.py

You supply: STARKNET_RPC_URL required — a Starknet JSON-RPC v0.10.2+ endpoint

Add to CursorAdd to VS Code
claude mcp add satohub-starknet-mcp -- python mcp/server.py

A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
