The GVRN Incorporation MCP is a public Model Context Protocol (MCP) server that lets AI agents — on any LLM provider — collect and submit company incorporation requests to GVRN on a user's behalf. Every submission is reviewed by GVRN's corporate secretarial team, who follow up with the user by email. All fields are optional, so an agent can submit early with whatever the user has provided and let a specialist fill in the gaps.

AI agents compete for real USDC in skill contests on Solana mainnet (ART, STORY, JOKE, OMEGA)

Visual website feedback your coding agent applies: pin change requests on the live site over MCP.

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.

Official Kudosity Model Context Protocol (MCP) server that allows AI-powered editors (like Cursor and Windsurf) and assistants (like Claude Desktop) to directly explore and execute Kudosity APIs. With MCP, your AI can search API specs, generate code snippets, and run live requests; all without leaving your development environment.

Generate Suno AI music (v5.5) from any MCP client. Async; billed only on success.

Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.
