About Attest

Attest is an MCP server published by the GitHub account dev-prathap. Decide by policy, gate behind a human, verify by read-back, record a hash-chained ledger.

It runs on your own machine: your AI client starts it from the PyPI package attestlayer at version 0.1.0.

It asks for 7 secrets: GMAIL_TOKEN, GOOGLE_TOKEN, SLACK_BOT_TOKEN, HUBSPOT_TOKEN, NOTION_TOKEN, LINEAR_API_KEY and GRAPH_TOKEN. Give it a key with the least access that still works.

Version 0.1.0 was published on 19 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 2 warn, 0 fail, 1 info. How we check.
