Questions

What is the MyChatArchive MCP server?

Local-first AI memory archive. Import ChatGPT, Claude, and Grok exports, generate semantic embeddings, and search via MCP server. Zero cloud, zero cost.

What tools does MyChatArchive expose?

6 in total: 6 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is MyChatArchive safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does MyChatArchive need?

It reads OPENAI_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does MyChatArchive run?

It speaks sse and stdio, so it runs as a local process your client starts. It is published on PyPI as mychatarchive.

How current is this page?

The grade is for one exact copy of the source (99fb644d16d6), read on 2026-10-07. The repository is watched and re-audited when it changes.
