MCP server directory

AI agent identity, trust, and audit trail infrastructure. 17 MCP tools: register agents with Ed25519 keypairs, check permissions (sub-5ms), emit tamper-evident audit events, verify trust scores (0-100), delegate credentials, and manage ephemeral agents. IETF Internet-Draft filed (draft-vorim-vaip-00). Works with LangChain, OpenAI, CrewAI, Stripe ACP, and 4 more frameworks. `npx @vorim/mcp-server`.

Cryptographic receipts for AI outputs: notarize any model inference with a signed Ed25519 attestation, sha256 content hash, and Merkle chain-anchor on Base or Solana. $0.001 per call via x402 USDC micropayments; verification is free and needs no wallet. Notarizes the hash, never your prompts. `npx -y @forgemeshlabs/x402-notary-mcp`

Microsoft Patch Tuesday triage from the official MSRC Security Update Guide. Monthly rollups, CVE/KB lookups, supersedence chains, product watchlists, and urgency-ranked results enriched with EPSS scores and the CISA KEV catalog. No API keys; also available as a free hosted remote endpoint. `uvx patch-tuesday-mcp`

Local-only GitHub Actions and CI maintenance scanner for AI-built apps. Exposes `scan_repo`, `explain_finding`, and `generate_fix_plan` to MCP clients; reads only allowlisted workflow and update configuration, modifies nothing, makes no outbound requests by default, and has zero runtime dependencies. Run with `npx -y taskbounty-check@0.1.6 mcp`.

Tells AI agents how independently a claim is being reported: syndication-aware source counting (a wire story reprinted by 40 outlets counts as one origin), 0-1 confidence scores, and published error rates in-repo. Measures corroboration, not truth — no stance detection. Keyless, no accounts. Install: `npx -y corroborate-mcp`.

Connect Claude, ChatGPT, and other AI assistants to the Twelve Data financial API — real-time and historical prices, 60+ technical indicators, fundamentals, earnings, dividends, ETFs, company news, market movers, and more. You need a Twelve Data account. Sign up at twelvedata.com. There are two ways to use it. Most people should use the cloud server (Option 1) — there is nothing to install. Connect your AI assistant to our hosted server: That's it. No installation, no API key to copy and paste. When you connect, a browser window opens and you log in with your Twelve Data account — your personal API key is linked automatically and stays tied to your account.
