CovaSyn MCP
Remote Model Context Protocol server (streamable HTTP, MCP protocol version 2025-06-18, server-sent events supported) that connects Claude, ChatGPT, Cursor, VS Code and other MCP clients to CovaSyn's deterministic chemistry tools for spectra, stability, toxicology (ICH M7), solubility and retrosynthesis. Authenticated with an API key from the CovaSyn dashboard (X-CovaSyn-Key or Authorization Bearer) or OAuth 2.1 with PKCE and dynamic client registration; every call counts against the plan's weekly allowance.
