MCP server directory

Local credential approval and execution gateway for AI coding agents. Agents receive typed handles instead of raw API tokens, SSH keys, and cloud credentials; one-time approvals bind the credential, command, arguments, working directory, environment bindings, and target. Injects credentials only into the approved child process, sanitizes output, and records a local audit trail. Install with `npm install -g @s-gw/s-gw`.

Compliance and identity for AI agents — verify an agent's certificate scope, read its behavioral risk score, and append to an immutable audit trail. X.509 identity issued via AWS KMS; MiCA / EU AI Act aligned. `npx -y @kakunin/mcp`

Zero-knowledge proof generation MCP server for AI agents. Lets agents prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal information. Server-side proving in AWS Nitro Enclave TEE, paid via x402 USDC on Base. Built on Noir circuits (Aztec) and ERC-8004 agent identity. Reference application [OpenStoa](https://github.com/zkproofport/openstoa) won 1st place at The Synthesis Hackathon ("Agents That Keep Secrets" track).

Check whether anything you depend on is known malware, before an agent installs it. `check_lockfile` takes a package-lock.json, yarn.lock or pnpm-lock.yaml and matches every pinned version against published malicious-package advisories in one call, free and with no API key, catching compromised releases like chalk@5.6.1 while leaving their clean releases alone. `scan_artifact` adds deterministic behavioral analysis (no LLM in the serving path) for credential theft, exfiltration, obfuscation, prompt injection and install-time droppers, with the file, line and evidence that triggered it; verdicts are SHA-256-bound so you can re-verify what landed on disk. Paid scans settle at $0.03 USDC on Base (x402) or prepaid credits. `npx lazaretto-mcp`

Post-quantum readiness for AI coding agents: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH), explain the harvest-now-decrypt-later exposure, get NIST ML-KEM/ML-DSA/SLH-DSA (and hybrid) migration guidance, verify fixes, and check dependencies. Content-based/advisory tools only. Run local (`npx @quantakrypto/mcp`) or the hosted OAuth endpoint at [mcp.quantakrypto.com](https://mcp.quantakrypto.com).

Trust infrastructure for AI agents — register DIDs, verify identities, query reputation scores, rate agents, manage W3C Verifiable Credentials, and handle USDC credit deposits on Base.

AI-powered smart contract security forge with 8-agent adversarial pen test. Generate, audit, fix, and compile contracts across 8 chains (Ethereum, Solana, Polygon, Base, Arbitrum, Optimism, BSC, Avalanche). Token intelligence with honeypot detection. x402 USDC payments for autonomous agents.

Local-first, zero-egress security scanner for AI-generated / "vibe-coded" JS/TS. Bundles Opengrep, Gitleaks & Trivy behind one CWE-keyed schema and adds AI-code-specific checks (client-side secret exposure, Supabase RLS, prompt-injection & LLM-output XSS sinks). No account, no telemetry.

Trust verification and security scanning for AI agents. Checks security posture of third-party MCP servers and tools with signed attestations (Ed25519/JWS) before interaction.

**Verifiable oracle MCP server**: Platon VRF (`get_random`), Chronos VDF (`compute_vdf` / `verify_vdf`), LUMEN reputation (`get_reputation_scores`) as agent tools. Pay-per-call over AIMarket Hub; every result independently verifiable. stdio · Python · [Glama](https://glama.ai/mcp/servers/alexar76/aimarket-oracle-gateway).

An MCP server that enables secure credential retrieval from 1Password to be used by Agentic AI.

Human sign-off + trust receipts for AI agents: requires a named human's approval before an irreversible action (payment release, record change, deploy), then mints an offline-verifiable Ed25519 Trust Receipt. Also exposes trust profiles, receipt verification, disputes, and delegation. Apache-2.0; policy engine formally verified. Install: `npx -y @emilia-protocol/mcp-server`.
