"Y Combinator" matching MCP servers:

Hermetic memory for AI agents — one Rust binary, one SQLite file, zero network. Recall returns evidence with provenance or abstains: no code path for making things up.

Enables users to import scientific figures together with their code, review and publish them as immutable releases into one user-chosen local library, then search, preview and materialize an exact confirmed template into any project from Claude Science, Cursor, Codex or other stdio MCP hosts. It keeps the catalog on disk and never executes plotting code, so the host agent inspects files while the server hashes, versions, gates and publishes them.
