## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 694 tokens (~49/item across 14 items; 14 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "gaip_run_governed_agent_loop" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 15 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Common questions

### What is the GAIP Broker MCP server?

GAIP Broker is an MCP server listed in the public MCP registry as io.github.tjcgraham-rgb/gaip-broker. GAIP delegation evidence, £0 read-only execution and receipt verification; no caller decision. This page covers its hosted endpoint (https://gaip-agent-to-art-prototype-production.up.railway.app/mcp).

### Is the GAIP Broker MCP server safe to use?

GAIP Broker scores 67 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GAIP Broker MCP server expose?

GAIP Broker exposes 14 tools: gaip_get_capabilities, gaip_get_shadow_status, gaip_get_governance_limits, gaip_get_identity_and_registry_status, assess_agent_card, and 9 more. Their descriptions and schemas cost roughly 672 tokens of context every time the server is loaded.

### Does the GAIP Broker MCP server require authentication?

No. We connected to GAIP Broker without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GAIP Broker MCP server still maintained?

GAIP Broker is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
