Setup
Install Atomic APIs in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/benzene66/atomicapis-mcp-server
Follow the installation instructions in the repository README, then restart your MCP client.
AModel Context Protocol (MCP)server that exposes 17 production-grade micro-API tools for AI assistants. Built with .NET 9 and the officialModelContextProtocolSDK.
MCP allows AI assistants like Claude to invoke these tools natively during conversation — no HTTP requests, API keys, or boilerplate needed on the client side.
Add this to yourclaude_desktop_config.json:
{ "mcpServers": { "atomicapis": { "command": "dotnet", "args": ["run", "--project", "/path/to/atomicapis-mcp-server/src"] } } }
claude mcp add atomicapis -- dotnet run --project /path/to/atomicapis-mcp-server/src
The server communicates over stdio using the MCP JSON-RPC protocol. It is designed to be launched by an MCP-compatible client (e.g., Claude Desktop, Claude Code, Kiro, or any MCP host). SeeQuick Installabove for configuration.

Toolsdefine the MCP interface — parameter descriptions, validation, and response formatting. Each tool delegates to anEngineclass that contains the pure business logic with no framework dependencies.
This is a web browser that enables your coding agent, such as Claude Code, to visit websites on your behalf and assist you in identifying bugs or creating UI test cases.
Create crafted UI components inspired by the best 21st.dev design engineers.

MCP server that gives AI assistants on-demand access to 1,500+ amCharts docs, ~300 code examples, and 1000+ class API references.
APIMatic MCP Server is used to validate OpenAPI specifications using APIMatic. The server processes OpenAPI files and returns validation summaries by leveraging APIMatic’s API.
One shared context layer for AI agents and humans — live API specs, DB schemas, and versioned contracts across repos so every agent and teammate works from the same source of truth.
