Syrin - Static Contract Analysis for MCP Servers

🚀 Syrin CLI is live on DevHunt Syrin CLI is a testing, linting, and static contract checker for MCP servers. It helps you validate MCP tools before they are used by an LLM — catching broken schemas, unsafe contracts, and non-deterministic behaviour early. What Syrin CLI does 1. Lints MCP tool schemas 2. Statistically validates tool contracts 3. Tests MCP servers without an LLM in the loop 4. Catches unsafe or ambiguous tool definitions early Why this matters? MCP servers are becoming the backbone of LLM tooling, but: 1. Schemas drift 2. Contracts break silently 3. LLMs fail in non-obvious ways 4. Syrin CLI treats MCPs like APIs that deserve real tooling, not prompt-time guesswork. Links: 1. GitHub: https://github.com/syrin-labs/cli 2.
