How this service works

MCP server security scan: probe any MCP endpoint's initialize handshake and tools/list and report whether it requires authentication, which protocol version it speaks, how many tools it exposes and which are not marked read-only. Use it before connecting an agent to an unknown MCP server. Input: url of the MCP endpoint.

Output

Returns details from the MCP server's initialize handshake including protocol version, whether authentication is required, and a list of tools exposed by tools/list that are not marked read-only — enabling security assessment before integration.

Example use cases

Pre-deployment MCP security audit

“Before I connect my agent to the MCP server at https://mycompany.com/mcp-api, can you check whether it requires auth, what protocol version it uses, and list any tools that could make changes rather than just reading data?”

Vetting a third-party MCP integration

“I found an MCP server at https://vendor-tool.io/mcp — can you probe its initialize handshake and tell me if it's open to unauthenticated access and which of its tools have write capabilities?”

Comparing two MCP server configurations

“Can you inspect https://staging.internal.com/mcp and report back the protocol version it speaks plus any tools that aren't flagged as read-only? I want to make sure the staging setup matches our security requirements.”

When to prefer

Use this endpoint when you need to security-audit or vet an MCP server before connecting an agent to it — specifically to assess authentication posture, protocol compatibility, and tool write-access risk. Prefer this over generic HTTP security checkers when the target is specifically an MCP server and you need protocol-level handshake details and tool-level access analysis.

Side effects

Unreachable URL returns a connection or timeout error
Non-MCP server at the URL causes handshake failure or malformed response
Server requires auth before returning tool list, limiting inspection depth
Invalid URL format causes input validation error
Server returns non-standard protocol version causing parsing issues
