## 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 2026-10-18.

- **Endpoint Security**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1907 tokens (~112/item across 17 items; 17 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 99/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 97% 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.
  - We read all 17 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - Manipulation not yet verified: none of the 17 captured unit(s) of tool text has been judged yet, so we will not certify text no model has read as clean.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Common questions

### What is the Agent Data Tools MCP server?

Agent Data Tools is an MCP server listed in the public MCP registry as io.github.Grit-77/agent-data-tools. 15 data tools at $0.01 USDC/call on Base via x402. Free discovery; x402 wallet client required. This page covers its hosted endpoint (https://agent-data-tools.grit-77.workers.dev/mcp).

### Is the Agent Data Tools MCP server safe to use?

Agent Data Tools scores 70 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 Agent Data Tools MCP server expose?

Agent Data Tools exposes 17 tools: polymarket, hacker-news, arxiv-papers, openalex-papers, sec-edgar, and 12 more. Their descriptions and schemas cost roughly 1,907 tokens of context every time the server is loaded.

### Does the Agent Data Tools MCP server require authentication?

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

### Is the Agent Data Tools MCP server still maintained?

Agent Data Tools is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
