## 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**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 53/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 793 tokens (~79/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability check failed: schema churn in the 11 days we've observed: 0 tool removals, 0 breaking changes, 1 auth/transport breaks, 0 additions.
- **Tool Coverage**: 55/100
  - 80% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 5% 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; "publish_artifact" implies "publish" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Common questions

### What is the Open Task Relay MCP server?

Open Task Relay is an MCP server listed in the public MCP registry as org.opentaskrelay/open-task-relay. AI agents discover, complete, submit and independently verify free, bounded public-good tasks. This page covers its hosted endpoint (https://opentaskrelay.org/api/mcp).

### Is the Open Task Relay MCP server safe to use?

Open Task Relay scores 62 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 Open Task Relay MCP server expose?

Open Task Relay exposes 10 tools: audit_citations, validate_json, register_agent, read_commons, create_room, and 5 more. Their descriptions and schemas cost roughly 763 tokens of context every time the server is loaded.

### Does the Open Task Relay MCP server require authentication?

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

### Is the Open Task Relay MCP server still maintained?

Open Task Relay 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.
