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 2026-10-07. - **Endpoint Security**: 57/100 - 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 1 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. - 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**: 54/100 - 50% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 8353 tokens (~214/item across 39 items; 36 tools + 3 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 23/100 - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 94/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 81% of tool parameters carry a description. - **Tool Safety**: 75/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "send_feedback" implies "send" and declares readOnlyHint instead, contradicting what its own name says it does. - An AI judge read all 38 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. ## Install ### How do I install the Maxwell Directory (x402 + MCP) server? Maxwell Directory (x402 + MCP) is a hosted endpoint at https://api.maxwellinternational.ai/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. ### Claude ```bash claude mcp add --transport http ai-maxwellinternational-data 'https://api.maxwellinternational.ai/mcp' ``` ### Cursor ```json { "mcpServers": { "ai-maxwellinternational-data": { "url": "https://api.maxwellinternational.ai/mcp" } } } ``` ### VS Code ```json { "servers": { "ai-maxwellinternational-data": { "type": "http", "url": "https://api.maxwellinternational.ai/mcp" } } } ``` ### Codex ```toml [mcp_servers.ai-maxwellinternational-data] url = "https://api.maxwellinternational.ai/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "ai-maxwellinternational-data": { "type": "remote", "url": "https://api.maxwellinternational.ai/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add ai-maxwellinternational-data --url 'https://api.maxwellinternational.ai/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: ai-maxwellinternational-data: url: "https://api.maxwellinternational.ai/mcp" ``` ### Netclaw ```json { "McpServers": { "ai-maxwellinternational-data": { "Transport": "http", "Url": "https://api.maxwellinternational.ai/mcp" } } } ``` ### Vellum ```bash assistant mcp add ai-maxwellinternational-data -t streamable-http -u 'https://api.maxwellinternational.ai/mcp' ``` ### Other ```json { "mcpServers": { "ai-maxwellinternational-data": { "type": "http", "url": "https://api.maxwellinternational.ai/mcp" } } } ``` The mcpServers block is a cross-client convention.
