Infraveil MCP server

A hardened, self-hosted Model Context Protocol server that lets your own AI agent query and govern your Infraveil control plane in-loop — read the governed state of your backend, and file deploy and remediation requests that always pass through human approval.

It is built on the same principle as the rest of Infraveil: trust by inspection, not assertion. This server adds no new authority and no new auth surface. It signs every request with the token your agent already holds, and it verifies the control plane's signed responses in return — so neither side can be forged on the wire. You can read every line here and diff the signing code against the published agent source; they are the same scheme.

Why this exists

The MCP ecosystem's security is, bluntly, bad — most public MCP servers require no auth at all. An MCP server that hands an AI agent operational reach into your backend is exactly the thing that should not be unauthenticated. This one:

• Signs both directions (HMAC-SHA256 over a canonical request/response, keyed by your per-agent token; nonce + timestamp replay protection).

• Cannot apply a change by itself. request_deploy and remediate enqueue a request into the control plane's human-approval queue and return the approval URL. There is no code path here that mutates your infrastructure.

• Is least-privilege. The token is scoped to one client/agent; tenancy is enforced by the control plane. This process holds no more authority than the agent already running on the host.

Install

pip install infraveil-mcp

Configure

The server reuses your existing Infraveil agent identity — it never mints credentials. Either set the environment variables:

export INFRAVEIL_BASE_URL=https://api.infraveil.com
export INFRAVEIL_CLIENT_ID=...
export INFRAVEIL_AGENT_ID=...
export INFRAVEIL_AGENT_TOKEN=...        # your agent's existing token

…or point it at your rendered agent source and let it read the ids and token straight out of the file you can already inspect:

export INFRAVEIL_AGENT_FILE=/opt/infraveil/agent.py

Tools

Read (no side effects):

Governed (enqueue for human approval — never auto-applied):

Verify it yourself

1. Read infraveil_mcp/client.py. The request-signing and response-verification code is plain stdlib hmac/hashlib.

2. Diff it against the published Infraveil agent source (_signed_headers, verify_response_signature). They implement the same protocol.

3. Run the test suite: pytest tests/. It transcribes the server's verifier and asserts this client's signatures are accepted and tampering is rejected.
