## 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 2026-10-17.

- **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 126 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**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 14835 tokens (~117/item across 126 items; 126 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 126 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 127 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.

### What is the AgentsToolsHub MCP server?

AgentsToolsHub is an MCP server listed in the public MCP registry as io.github.Thyphex/agenttools-hub. 126 paid-per-call JSON APIs for AI agents over x402: calculators, live data, crypto, security, dev. This page covers its hosted endpoint (https://agentstoolshub.com/api/mcp).

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

AgentsToolsHub scores 69 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 AgentsToolsHub MCP server expose?

AgentsToolsHub exposes 126 tools: calculators_percentage_calculator, dev_base64_encode, databases_countries, calculators_discount_calculator, calculators_tip_calculator, and 121 more. Their descriptions and schemas cost roughly 14,595 tokens of context every time the server is loaded.

### Does the AgentsToolsHub MCP server require authentication?

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

### Is the AgentsToolsHub MCP server still maintained?

AgentsToolsHub is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
