How this service works
Connect to a remote MCP server (Streamable HTTP) as a client and return its name, version, instructions, capabilities and tool list with descriptions and parameters, without calling any tool. Know what an MCP server offers before trusting it.
Output
Returns a JSON object with: the server URL, a server object (name, version), an accessibility boolean, the MCP protocol version string, a list of capability names, server instructions text, the total number of tools, and an array of tool objects each containing a name, description, parameter list, and required parameters array.
Example use cases
Audit unknown MCP server before use
“I found this MCP server at https://mcp.example.com/mcp and I want to know what tools it offers and what parameters they require before I let my agent use it — can you inspect it without calling anything?”
Discover tools for agent orchestration
“I'm building an agent pipeline and need to know every tool available on the MCP server at https://api.partner.com/mcp, including required parameters and descriptions. Can you fetch that list for me?”
Verify MCP server accessibility and protocol
“Check whether the MCP server at https://mcp.myservice.io/mcp is reachable and tell me its protocol version, server name, and what capabilities it declares.”
Technical details
Endpoint
POSThttps://api.vextorium.com/mcp-inspeccionar-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and audit what a remote MCP server offers before committing to calling its tools — especially useful for unknown or untrusted servers. It is ideal for agent orchestration pipelines that need to dynamically route to the right tool, for security audits of third-party MCP servers, or for building catalogs of available MCP capabilities. Prefer this over manually calling the MCP server's initialize handshake when you want a clean, structured JSON summary without side effects.
Side effects
- MCP server URL is unreachable or returns non-200 — accesible will be false with no tool data
- Target server does not implement the MCP Streamable HTTP protocol — may return empty or malformed response
- Invalid URL format in request body causes schema validation error
- Server is accessible but exposes zero tools — returns empty herramientas array
- Network timeout if the remote MCP server is slow to respond
