About Attestari
Attestari is an MCP server published by the GitHub account attestari. Auditable memory for AI agents: provable deletion, tamper-evident audit, time-travel recall.
It runs on your own machine: your AI client starts it from the PyPI package attestari at version 0.0.8.
It asks for 3 secrets: ATTESTARI_KEK, ATTESTARI_DATABASE_URL and ANTHROPIC_API_KEY. Give it a key with the least access that still works.
Version 0.0.8 was published on 9 October 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: 7 pass, 1 warn, 0 fail, 1 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
ATTESTARI_KEK | No | Yes | Base64 32-byte root key. Set it to enable encryption at rest and cryptographic erasure (forget() destroys the subject's key and signs the certificate). Without it, forget() is a logical delete and certificates are left unsigned. |
ATTESTARI_DATABASE_URL | No | Yes | Postgres DSN. Set it to use Postgres + pgvector instead of the default local SQLite file (concurrent access, indexed hybrid search). |
ATTESTARI_SQLITE_PATH | No | No | Where the default SQLite ledger lives. |
ATTESTARI_MCP_ALLOW_FORGET | No | No | Set to 1 to offer the forget_subject tool (off by default, since erasure is irreversible and an agent can be steered by what it reads). When on, it is flagged destructive and takes two calls: a preview that returns a manifest hash, then a confirmation that passes it back. |
ANTHROPIC_API_KEY | No | Yes | Enables Claude-powered fact extraction; falls back to the built-in regex extractor when unset. |
