MCP Server

Quick Reference

WhatMCP Server for AI tools

WhyQuery A55 docs from AI assistants and IDE integrations

A55 exposes its documentation through a Model Context Protocol (MCP) server. This lets AI assistants, IDE extensions, and automation tools query current API schemas, guides, and diagrams programmatically instead of relying on stale training data.

Why MCP

Use case	Benefit
AI grounding	Get current docs instead of stale training data
IDE integration	Reference A55 docs directly in your editor
Tooling	Structured access for CI/CD and automation scripts
Search	Search across API reference pages, guides, and diagram summaries
API schemas	Inspect endpoint methods, paths, response codes, and request schemas from OpenAPI
Diagrams	Retrieve Mermaid diagrams with compact text summaries and source markup

Endpoint

https://docs.a55.tech/mcp

MCP client setup

Copy the URL above and paste it into your MCP client configuration. No API key is required for documentation access.

The endpoint uses MCP Streamable HTTP JSON-RPC over POST. A GET request returns a small health payload for diagnostics.

What you can use it for

• Ground AI coding assistant answers in current A55 documentation
• Pull reference snippets for error codes, status definitions, and API fields
• Build internal tooling that validates integration parameters against docs
• Search documentation semantically from terminal or scripts

Configure in AI tools

Cursor IDE

Add to your .cursor/mcp.json:

{
  "mcpServers": {
    "a55-docs": {
      "url": "https://docs.a55.tech/mcp"
    }
  }
}

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "a55-docs": {
      "url": "https://docs.a55.tech/mcp"
    }
  }
}

Generic MCP Client

1. Set the server URL to https://docs.a55.tech/mcp
2. Use the server name label A55 Docs
3. No authentication headers required
4. Use Streamable HTTP / JSON-RPC transport

Available tools and resources

Tool/resource	Description
search_docs	Search API reference pages, integration guides, and Mermaid summaries
get_doc	Read a documentation page by ID, route, or source path
list_api_operations	List operations from the OpenAPI source contract, optionally filtered by tag
get_api_operation	Read one endpoint contract with request schema and required fields
get_mermaid_diagrams	Retrieve Mermaid diagrams with summaries and source markup
Resources	Read docs and API operations as a55-docs://docs/... and a55-docs://api/... resources

Read-only docs access

The MCP server provides read-only access to documentation. It does not replace API keys or grant access to the A55 payment API.

Client naming

When configuring your client, use the server name label A55 Docs for consistent identification across tools.
