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 2026-08-03. - **Endpoint Security**: 74/100 - 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 is enforced; there's no plaintext access path. - 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**: 66/100 - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 12957 tokens (~166/item across 78 items; 78 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 27/100 - Stability observed for 8 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). - 98% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### Claude ```bash claude mcp add --transport http webberdesign-webbersites-x402-data-api https://api.webbersites.com/mcp ``` ### Codex ```toml [mcp_servers.webberdesign-webbersites-x402-data-api] url = "https://api.webbersites.com/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "webberdesign-webbersites-x402-data-api": { "type": "remote", "url": "https://api.webbersites.com/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add webberdesign-webbersites-x402-data-api --url https://api.webbersites.com/mcp --transport streamable-http ``` ### Hermes ```yaml mcp_servers: webberdesign-webbersites-x402-data-api: url: "https://api.webbersites.com/mcp" ``` ### Other ```json { "mcpServers": { "webberdesign-webbersites-x402-data-api": { "type": "http", "url": "https://api.webbersites.com/mcp" } } } ``` The mcpServers block is a cross-client convention.
