API.market is released under the MIT license. This is a permissive open-source license, meaning you can freely use, modify, and distribute the software.
Add new capabilities to Claude beyond text generation
Example
Access external data sources, execute code, interact with tools and services
Transform Claude from chatbot to action-taking agent
Provide Claude with access to relevant context and data
Example
Load project documentation, access knowledge bases, query databases
Get more accurate, context-aware responses
Automate multi-step workflows combining AI and external tools
Example
Research → Summarize → Create document → Send notification
Complete complex tasks end-to-end without manual steps
Share your MCP server with the developer community
API.market is a well-scoped MCP server in the explainx.ai directory — install snippets and categories matched our Claude Code setup.
Useful MCP listing: API.market is the kind of server we cite when onboarding engineers to host + tool permissions.
API.market reduced integration guesswork — categories and install configs on the listing matched the upstream repo.
API.market is a well-scoped MCP server in the explainx.ai directory — install snippets and categories matched our Claude Code setup.
We wired API.market into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.
I recommend API.market for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.
Strong directory entry: API.market surfaces stars and publisher context so we could sanity-check maintenance before adopting.

A Model Context Protocol (MCP) server that exposes API-Market's endpoints as MCP resources. This server allows Large Language Models to discover and interact with APIs defined by OpenAPI specifications through the MCP protocol.
This repository provides access to the APIs available at API.market. The tool is free to use and allows agents to communicate freely with all available APIs, making it super powerful. With over 200+ APIs available at API.market, you can leverage a wide range of functionalities.
You do not need to clone this repository to use this MCP server. You can simply configure it in your client of choice.

"command": "npx",
"args": [
"-y",
"@noveum-ai/mcp-server",
"--headers",
"x-magicapi-key:<your-api-key>"
]
},
npx -y @noveum-ai/mcp-server --headers x-magicapi-key:your-api-key
To obtain an API key
We can use the agent to find a route between any two points

We can use the agent to find news about any topic, and then dig deeper into the articles

We can use the agent to look for available domains

The utils folder contains helper scripts for managing API configurations, parsing OpenAPI specifications, and registering new APIs into the MCP server.
Find the OpenAPI JSON for the API you want to integrate. After that, create a folder json_files in the root directory of the project and add your OpenAPI JSON spec to the folder
After obtaining the OpenAPI spec, use modify_api.py to update the path inside the spec to include the file name.
python utils/modify_api.py
After modifying the paths, update the API summaries by choosing one of the following options:
python utils/LLM_summary_shortener.py
python utils/manual_summary_shortener.py
Rebuild the project to apply the changes:
npm run build
Then, test the new API integration using:
npm run inspect
If you want to contribute this new API to the repository:
If you want to publish your changes:
package.json accordingly (e.g., update the version, name, etc.).npm publish --access public

💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
