mandateshield-com-mcp.yml
One hosted, stateless Streamable HTTP MCP server at https://mandateshield.com/api/mcp. Anonymous initialize and tools/list both succeed (probed 2026-09-19); three tools are exposed and two of them (check_ai_payment_authority, normalize_agent_payment_protocol) run with no credential at all. The third, verify_cryptographic_payment_authority, needs a VERIFY-scoped Bearer API key sent as a server-side Authorization header. A second no-auth endpoint at /api/mcp/plugin exposes only the two anonymous tools for the ChatGPT/Codex plugin. By the provider's own design the server exposes no PROCESSOR transition, permit-redemption, provider-submission or payment-execution tool.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
