"How to connect to a REST API" matching MCP connectors:

Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.

Verify anything: email, phone, domain, URL and IBAN validation, phishing/malware URL screening, and OFAC sanctions checks. Pay-per-check in USDC on Base via x402 — no signup, no API keys.

Discovery, OAuth, project operations, and exact project MCP handoff for Spala backend projects.

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.

Scan public websites for privacy, cookie, tracker, consent, policy, and disclosure risk signals. Start instantly with zero-auth Light mode—no account or API key required.

Control Plane (controlplane.com): deploy and operate workloads across AWS, GCP, Azure, and more.

Is a wallet frozen by Tether/Circle? Free freeze checks + full history, screening & KYT. 9 chains.

Pay-per-call safety checks for AI agents: screen a crypto address or URL before you transact.

Runtime permission, approval, and audit layer for AI agent tool execution.

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.

Capture a web source, or seal a hash you hold, into a signed receipt anyone can verify offline.

CSOAI (UK 16939677) GSPC measurement over MCP: assess, board (13 of 14), verify cards.

Inventory and audit your agent fleet over MCP: audit_mcp_config returns risk-ranked findings with a 0-100 posture score, scope_check ranks tool-manifest blast radius, audit_skill_file and injection_scan screen untrusted skill files and text, and inventory_report builds a governance inventory with risk tiers. All analysis is deterministic and local to the request.

Pre-action allow/deny for AI agents. 24 statutes, 13 jurisdictions: EU AI Act, GDPR, DPDP.

Per-transaction crypto trade validator for AI agents. Returns deterministic PROCEED / CAUTION / BLOCK verdicts using WaveGuard anomaly detection, history checks, and rug-pull risk analysis.

Pay-per-call security verification for wallets, contracts, agents and apps, in USDC over x402.

Check how many years of verifiable history a person has behind accounts they already own.

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

Keyless email checks: disposable, role, and free-provider detection, MX, and typo suggestions.
