## 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**: 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 4 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**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 457 tokens (~114/item across 4 items; 4 tools + 0 resources), lean.
  - 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**: 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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.

## Install

### How do I install the dev.workers.sebastiaan-ba3.mcpgateway/tools MCP server?

dev.workers.sebastiaan-ba3.mcpgateway/tools is a hosted endpoint at https://mcpgateway.sebastiaan-ba3.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (4)

### `apecheck_report` (~156 tokens)

Paid (x402, USDC on Base). Full safety report for a Base ERC-20 token contract: metadata, raw owner address, mint-selector heuristic, approximate recent-activity signal. Call without 'tx' first to receive the exact x402 payment challenge (amount, asset, payTo address, chain); pay that amount in USDC on Base, then call again with the resulting transaction hash in 'tx' to receive the real report.

Input parameters:

- `address` (string, required): 0x-prefixed 40-hex-character Base token contract address.
- `tx` (string): Optional: 0x-prefixed 64-hex-character Base transaction hash proving payment. Omit on the first call to see the payment challenge.

### `secheaders_report` (~129 tokens)

Paid (x402, USDC on Base). Full HTTP security-headers report for a URL: every header checked, raw values, remediation detail. Call without 'tx' first to receive the exact x402 payment challenge; pay, then call again with the transaction hash in 'tx' to receive the full report.

Input parameters:

- `tx` (string): Optional: 0x-prefixed 64-hex-character Base transaction hash proving payment. Omit on the first call to see the payment challenge.
- `url` (string, required): The URL to check (e.g. https://example.com).

### `llmstxt_check` (~92 tokens)

FREE, no payment required. Checks whether a site has a valid llms.txt file (the emerging convention for telling AI crawlers/agents what a site is and how to use it): fetches it, reports status and any errors/warnings.

Input parameters:

- `url` (string, required): The site URL to check (e.g. https://example.com). llms.txt is looked up at that domain's root.

### `crawlercheck_check` (~80 tokens)

FREE, no payment required. Checks a site's robots.txt against a list of known AI crawlers (GPTBot, ClaudeBot, Google-Extended, etc.) and reports which are allowed or blocked.

Input parameters:

- `url` (string, required): The site URL to check (e.g. https://example.com). robots.txt is looked up at that domain's root.
