BestMCPServers Tool API

Call BestMCPServers utilities directly from agents, scripts, ChatGPT Actions, OpenAPI clients, and future MCP clients. The first API layer exposes JSON formatting, JSON validation, Base64 encode/decode, and JWT decode tools.

HTTP POST API

Every tool accepts JSON input with a single content field and returns a consistent success/error envelope.

OpenAPI Ready

Import the OpenAPI spec into ChatGPT Actions, internal agents, or API clients without manual endpoint setup.

No Auth v0

No database, login, payment, or API key. Rate limiting is designed for a later Cloudflare layer.

MCP Server Direction

The HTTP API is the first step toward a hosted MCP tool provider. The same core functions can be exposed later through a remote MCP endpoint so Claude, Cursor, OpenClaw, and other clients can discover tools like format_json, validate_json, encode_base64, decode_base64, and decode_jwt.
