Conarium MCP server

Conarium The Third Eye for Your Company's Data. Part of VERAX, by VERAX Teknoloji. Sister projects: Tugra · Cedulon. A self-hosted, governed gateway that lets AI coding assistants (Cursor, Copilot, Claude) touch your real data under a policy you write—protected values masked before they leave. When a receipt sink is configured it writes a signed, independently verifiable receipt of every access it mediates; conarium-init sets that sink, so the default layout does.

The site lives at conarium.dev; this repository is the product.

Check it before you read the rest

Nothing below has to be taken on trust. There is a live receipt chain; verify it against its public key on your own machine, with no account and no data of yours:

npm i @conarium-ai/core
curl -fsS https://conarium.dev/proof/chain.jsonl   -o chain.jsonl
curl -fsS https://conarium.dev/proof/key.pem       -o key.pem
curl -fsS https://conarium.dev/proof/key.pem.keyid -o key.pem.keyid
npx conarium-verify chain.jsonl --pubkey key.pem

note: tail truncation is not visible — this run did not see receipts deleted from the
end of the file. Pin with --expect-count, --expect-last-hash, or --anchor-check.
ok: 3 receipt(s) verified (3 with undeclared model, 3 with undeclared client)

Exit code 0. The three receipts are one ordinary read, one where five email addresses and a card number were masked before the model saw them, and one refusal. Change any field and the recomputed hash stops matching the stored one — exit 10. Change the signature instead — exit 13.

The verifier is a single file that imports nothing from the package it is checking, so a compromised Conarium cannot talk it into a passing result. Note that it volunteers what it did not check, in the first line of its own output, before the good news.

Limitations

What this repository has not done is in LIMITATIONS.md (Türkçe). The dated comparison page is conarium.dev/compare.html — that is the only copy; this repo does not keep a second one.

Standards

Shortened. The full README is on GitHub.
