## 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**: 46/100
  - 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 48 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 check failed: the endpoint is reachable over plaintext HTTP.
  - 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 (good).
  - Context-footprint check failed: tool/resource definitions use about 9645 tokens (~200/item across 48 items; 48 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 93% 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 48 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 49 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### What is the Agent Tools MCP server?

Agent Tools is an MCP server listed in the public MCP registry as dev.workers.jbarkules.agent-tools/agent-tools. x402 agent tools: invoice/PDF extract, OCR, email risk, web to markdown, domain, FX, time. This page covers its hosted endpoint (https://agent-tools.jbarkules.workers.dev/mcp).

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

Agent Tools 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 Agent Tools MCP server expose?

Agent Tools exposes 48 tools: email_check, email_check_full, pdf_to_text, document_extract, domain_lookup, and 43 more. Their descriptions and schemas cost roughly 9,598 tokens of context every time the server is loaded.

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

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

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

Agent Tools is marked deprecated 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.
