A3.9/5.0

Scored across 5 tools

Disambiguation4/5

Single-schema conversion, batch conversion, and linting are clearly separated by scope and action. However, openapi_to_tools and mcp_manifest both accept OpenAPI input and can emit tool definitions, creating some overlap that could cause misselection.

Naming Consistency3/5

Three tools follow a clear verb_noun snake_case pattern (batch_convert_tool_schemas, convert_tool_schema, lint_tool_schema). mcp_manifest is noun-only and openapi_to_tools uses a source_to_target pattern, so the set is readable but not fully consistent.

Tool Count5/5

Five tools is well scoped for a schema conversion and validation server. Each tool handles a distinct workflow: single conversion, batch conversion, linting, MCP manifest generation, and OpenAPI conversion.

Completeness4/5

The surface covers the core lifecycle: convert, batch convert, lint, generate MCP manifests, and derive tools from OpenAPI. Minor gaps exist, such as batch linting or batch OpenAPI-to-tool conversion, but agents can work around them.

Available Tools

5 tools
batch_convert_tool_schemasBatch convert tool schemasA
Read-onlyIdempotent
Inspect

Convert up to 50 tool definitions at once to the chosen formats, with per-tool issues and ready-to-use bundles. Free: 5 calls/hour per IP with arguments up to 8 KB; then $0.05 USDC per call via x402.

Inputs: tools (required), targets.

convert_tool_schemaConvert tool schemaA
Read-onlyIdempotent
Inspect

Convert one LLM tool/function definition between OpenAI, OpenAI strict mode, Anthropic, Gemini, MCP and plain JSON Schema. The input format is auto-detected. Every change is reported as an issue with a JSON pointer. Free: 5 calls/hour per IP with arguments up to 8 KB; then $0.01 USDC per call via x402.

Inputs: tool (required), targets.

lint_tool_schemaLint tool schemaA
Read-onlyIdempotent
Inspect

Check one LLM tool definition against each provider's schema rules (OpenAI strict, Anthropic, Gemini, MCP) and report errors and warnings with fixes. Free: 5 calls/hour per IP with arguments up to 8 KB; then $0.005 USDC per call via x402.

Inputs: tool (required), targets.

mcp_manifestMCP manifest + server stubA
Read-onlyIdempotent
Inspect

Generate an MCP server manifest (tools with inputSchema, titles, annotations, HTTP bindings) and a TypeScript stdio server stub from an OpenAPI spec or a list of tools. Free: 5 calls/hour per IP with arguments up to 8 KB; then $0.15 USDC per call via x402.

Inputs: tools, server, include, openapi.

openapi_to_toolsOpenAPI to toolsA
Read-onlyIdempotent
Inspect

Turn an OpenAPI 3.x or Swagger 2.0 spec (JSON object) into LLM tool definitions in the chosen format, one tool per operation. Free: 5 calls/hour per IP with arguments up to 8 KB; then $0.02 USDC per call via x402.

Inputs: spec (required), target, include, maxTools.
