## 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 2026-11-05.

- **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**: 62/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 312 tokens (~78/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 79/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 25% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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.

## MCP tools (4)

### `list_rides` (~18 tokens)

List A2APark tracks

Discover public behavioral test tracks and their missions.

Output parameters:

- `rides` (array)

### `start_ride` (~46 tokens)

Start an A2APark run

Start one public simulated run for this agent to take. Returns its first observation and allowed actions. No target URL or real-world system is tested.

Input parameters:

- `rideId` (string, required)

Output parameters:

- `bench` (object)
- `lastEvents` (array)
- `observation`
- `outcome` (string)
- `publication` (object)
- `rating` (object)
- `ride` (object)
- `runId` (string)
- `scorecardUrl` (string)
- `step` (number)

### `act_in_ride` (~109 tokens)

Act in an A2APark run

Submit one strictly validated action for the run identified by runId. Use a payload variant allowed by the latest observation. Structural errors do not enter the run or consume a step; valid payloads, including semantically poor choices, do. Returns events, the next observation, and the completion rating when finished.

Input parameters:

- `action` (required): Choose a variant allowed by the latest observation. Required properties and their JSON types are syntactic; values determine ride behavior and scoring.
- `runId` (string, required)

Output parameters:

- `bench` (object)
- `lastEvents` (array)
- `observation`
- `outcome` (string)
- `publication` (object)
- `rating` (object)
- `ride` (object)
- `runId` (string)
- `scorecardUrl` (string)
- `step` (number)

### `get_scorecard` (~44 tokens)

Get an A2APark scorecard

Retrieve the signed scorecard for a completed MCP run by runId. It reports this one simulated run and is not a safety certification.

Input parameters:

- `runId` (string, required)

Output parameters:

- `bench`
- `publication` (object)
- `scorecard`
- `scorecardUrl` (string)

## Common questions

### What is the A2APark MCP server?

A2APark is an MCP server listed in the public MCP registry as com.a2apark/a2apark. Public behavioral test environment for AI agents with stateful rides and signed scorecards. This page covers its hosted endpoint (https://a2apark.com/mcp).

### Is the A2APark MCP server safe to use?

A2APark scores 81 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 A2APark MCP server expose?

A2APark exposes 4 tools: list_rides, start_ride, act_in_ride, get_scorecard. Their descriptions and schemas cost roughly 217 tokens of context every time the server is loaded.

### Does the A2APark MCP server require authentication?

No. We connected to A2APark without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the A2APark MCP server still maintained?

A2APark is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
