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**: 66/100 - 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 122 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 is configured correctly; the domain's records validate against the full chain to the root. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 37/100 - AI-judged instruction clarity (poor). - Tool/resource definitions use about 11571 tokens (~94/item across 122 items; 122 tools + 0 resources), lean. - 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**: 67/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 0% of tool parameters carry a description. - **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 com-calcfleet-calculators https://calcfleet.com/api/mcp ``` ### Codex ```toml [mcp_servers.com-calcfleet-calculators] url = "https://calcfleet.com/api/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "com-calcfleet-calculators": { "type": "remote", "url": "https://calcfleet.com/api/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add com-calcfleet-calculators --url https://calcfleet.com/api/mcp --transport streamable-http ``` ### Hermes ```yaml mcp_servers: com-calcfleet-calculators: url: "https://calcfleet.com/api/mcp" ``` ### Other ```json { "mcpServers": { "com-calcfleet-calculators": { "type": "http", "url": "https://calcfleet.com/api/mcp" } } } ``` The mcpServers block is a cross-client convention.

See the exact per-tier math. Supports Verifiable Calculation Certificates: pass certify=true to also receive a signed, independently verifiable receipt (DSSE/Ed25519) for this exact calculation. Input parameters: - `adjustmentAmount` (number, required) - `certify` (boolean) - `revenue` (number, required) - `tier1RatePct` (number, required) - `tier2RatePct` (number, required) - `tier2ThresholdAmount` (number, required) ## Diagnostics Captured diagnostic sections: TLS, DNSSEC, Authorisation, Transports.
