If you are building or using an MCP server, your AI agent depends on those tool definitions being correct. They usually are not. - Tool descriptions too vague for the LLM to pick the right one - Two tools look so similar the model picks one at random - Parameter schemas missing or wrong — LLM hallucinates values - A tool returns 12MB of JSON and blows the context window - Another tool silently writes to disk when it should not - Your logs look fine. The agent is broken. Syrin catches all of this before production. --- See It In Action --- Try It Right Now One command. No install, no config, no API keys: Have your own MCP server running? Point Syrin at it: If your server uses stdio instead of HTTP: Want to try more commands against a local example server?
