"An Introduction to the Python Programming Language" matching MCP connectors:

Identity infrastructure for the AI economy. Confirms if someone is known; returns inferred traits.

Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

Read-only MCP server for turva.dev, an agent-readiness audit and advisory service.

The PropelAuth Integration MCP Server helps you and your favorite AI agent integrate PropelAuth as quickly and easily as possible into your project. Whether you're integrating PropelAuth into your Next.js project or your FastAPI backend, the Integration MCP Server will ensure your AI agent has the best context possible for a successful integration.

Deterministic gate for AI agents: ALLOW/DENY a step before it runs, sealed to a verifiable receipt.

Trust verdict for an x402 payment endpoint: health, 402 handshake, price, proceed/caution/avoid.

Public MCP digital twin with synthetic systems and an agent firewall. No customer data.

IOCs (URLs, domains, IPs, hashes) shared by the infosec community on X/Twitter. No auth, CC0.

Validate whether an IP address belongs to PetalBot. Remote MCP server exposing a validate_ip tool.

Prove a real, unique human performed an action; mint a signed, verifiable Proof-of-Human credential.

Validate whether an IP address belongs to YandexBot. Remote MCP server exposing a validate_ip tool.

Validate whether an IP address belongs to Applebot. Remote MCP server exposing a validate_ip tool.

Pre-signature x402 payment-risk oracle. AI agents call forecast_payment before paying a counterparty and get a GO / HOLD / STOP verdict from settlement reputation, price-anomaly (quoted vs the payee's own median), and OFAC sanctions screening — plus a third-party-verifiable Ed25519 signed receipt. Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.

MCP server teaching AI agents to implement TideCloak: auth, E2EE, IGA, security analysis

Validate whether an IP address belongs to Googlebot. Remote MCP server exposing a validate_ip tool.

AI creation with focused Machine Language Labs, open worlds, A2A, MCP and x402.

Validate whether an IP address belongs to Bingbot. Remote MCP server exposing a validate_ip tool.

Hosted governance layer for LLM agents. Seven mechanically-enforced rules plus audit-chain verification, preflight file protection, session handoff, and an emergency kill switch.

Read-only breach intelligence from public feeds: reports THAT a domain leaked, never the data.

Trust Graduation gate: Claude can do real work once Mission decides what it is allowed to do.
