How this service works
Inspect MCP tools and return agent-readiness score, risky tools, missing schemas, and marketplace candidates.
Output
Returns a structured report including an agent-readiness score (0-1 or similar scale), a list of risky tools with explanations, tools with missing or incomplete schemas, and tools identified as candidates for listing on an agent marketplace.
Example use cases
Audit MCP server before agent deployment
“I'm about to integrate my MCP server with an AI agent platform. Can you scan my tool definitions and flag anything that might cause compatibility issues or safety problems?”
Find marketplace-ready tools in MCP spec
“We have a bunch of tools in our MCP server but only want to list the safest, most complete ones on the agent marketplace. Can you identify which tools have solid schemas and high agent-readiness scores?”
Debug MCP tool definition problems
“Our MCP tools aren't being picked up correctly by agents. Can you audit our tool definitions and tell us what's missing or broken so we can fix them?”
Technical details
Endpoint
POSThttps://agentspec-one.vercel.app/inspect/mcpWhen to prefer
Use this endpoint when you need to audit MCP server tool definitions specifically — not OpenAPI specs. Choose this over the generic AgentSpec scorer when you need granular MCP-specific risk analysis, schema gap detection, and marketplace suitability signals rather than just a top-level score.
Side effects
- Invalid or malformed MCP tool definitions return a validation error
- Empty or missing tool list returns a low/zero readiness score
- Unsupported MCP format versions may cause parsing failure
- Network timeout if MCP payload is very large
- Payment failure (x402) prevents access to the endpoint
