# invinoveritas

A hosted MCP server that hands your agent an independent verdict on a diff, shell command or transaction, plus a signed proof anyone can recheck.

## What it does

Before an irreversible step, the agent calls `review` and gets a verdict from a party that is not the agent itself: `approve`, `approve_with_concerns` or `reject`, with issues ranked by severity. The verdict is advisory — it never blocks anything on its own. Your code decides what happens next.

Nothing to install: this is a remote Streamable-HTTP MCP endpoint at `https://api.babyblueviper.com/mcp/verify`. Sign in with standard MCP OAuth where the client supports it, or use a free API key as a Bearer header. `verify_proof`, `ledger` and `payment_receipt` need no auth at all; `review` and `witness` do. Nine tools live on the endpoint, including `validate` and `audit_agent_readiness`.

The proof is a BIP-340-signed Nostr event pushed to a public ledger anchored to Bitcoin. You can check it offline against the published key, or POST it to `https://api.babyblueviper.com/verify-proof` for free. Zero-dependency verifiers ship as `invinoveritas-verify` on pip and npm. Skip the Bearer header and the paid calls simply won't go through — set that up first.

## When to use it
- get an outside read on a diff before opening a PR
- stop an agent on a risky shell command
- verify someone else's proof without trusting the presenter
- notarize exact claim bytes without judging them
- keep a record of a decision that can be rechecked later

## Example prompts
- Before you open the PR, call `review` on the diff with `artifact_type` set to `code_diff` and `sign: true`
- Run `review` on this shell command, `artifact_type` `shell_command`, and list the issues
- Recompute the proof with `verify_proof` and tell me whether the signature checks out
