io.github.MarkovianProtocol/provenance is an MCP server with 4 tools an agent can call, among them markovian_notarize, markovian_stamp, markovian_trace. It answers at https://api.markovianprotocol.com/mcp/ over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Stamp any data to the Markovian chain for a verifiable provenance receipt. Proves timing, not truth.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
markovian_notarize | Notarize any file or hash into a public transparency log cosigned by 7 independent witnesses and anchored to Bitcoin. Hash-only: pass a local file path (hashed on this machine; the file never leaves it) or a sha256 hex string — only 32 byte Inputs: path, sha256 |
markovian_stamp | Commit any data (an AI output, a decision, a record) into a public, witnessed transparency log and get back a verifiable, tamper-evident provenance stamp (canonical markovian-provenance/v1). It proves the data existed and was committed at t Inputs: data, wallet, label, derived_from |
markovian_trace | Walk and verify a stamp's full provenance lineage by merkle_root. Use this when a stamp was created with derived_from links, to map what an output was built from. Returns a MAP of the graph (not a yes/no verdict): each node carries hash_bin Inputs: merkle_root |
markovian_verify | Look up a Markovian stamp by its merkle_root against the public verifier, with no key or account. verified:true means the stamp record exists and the response echoes its committed data_hash — recompute your content's SHA-256 and compare it Inputs: merkle_root |

It answered our last check on 18 October 2026 in 551 ms. Over 10 checks since 5 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
4, as returned by the server's own tools/list on 31 August 2026: markovian_notarize, markovian_stamp, markovian_trace, markovian_verify.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.markovianprotocol.com/mcp/. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.markovianprotocol. Endpoint host: api.markovianprotocol.com. ARD identifier: urn:air:io.github.markovianprotocol:mcp:provenance.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
