The mcpc server is a C implementation of the MCP protocol itself, not a functional MCP server providing tools to agents. The single tool 'mcpc-info' is a self-referential metadata tool with virtually no useful functionality. The tool has a trivial description (37 chars) that describes the implementation artifact, not agent-facing utility. No input schema is visible in the provided source code. The codebase shows a library implementation (libmcpc.a, libmcpc.so) with test harnesses, but tool definitions are not explicitly registered with schemas or parameter metadata. This appears to be an educational or infrastructure project rather than a production agent tool server.

• If mcpc-info is meant to be a discovery/info tool, rename to 'describe_mcp_protocol' or 'get_protocol_version' and expand the description to 50-150 chars explaining what version and features are supported
• Add explicit input schema (even if empty/minimal) and document it in the tool definition. Include parameter types, descriptions, and constraints
• Document the output schema: what fields does mcpc-info return? (e.g. protocol_version, supported_capabilities, server_name, etc.)
• Clarify the intended use case: is this a diagnostic tool for clients to discover server capabilities? If so, rename and expand functionality to return actual capability metadata (resources, prompts, tools, etc.)
• Add error handling guidance: what happens if called on an unsupported protocol version?
• Consider whether a single 'mcpc-info' tool is sufficient. If this is a protocol implementation library, consider multi-tool support for actual agent work (not just self-description)
