APIs.io MCP Server

Read-only MCP server over the APIs.io catalog, served over Streamable HTTP at https://apis.io/mcp. 15 curated tools led by apis_io_search let agents discover APIs, providers, tags, ratings, industries, regions, and published artifacts. Generated from the same OpenAPI contract as the REST API. Keyless free tier; send an X-API-Key header for higher rate limits and the Pro-tier industries/regions/ratings tools.

Open endpoint → APIs.io provider profile

One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

Endpoint

https://apis.io/mcp

Transport: Hosted endpoint

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "apis-io": { "url": "https://apis.io/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "apis-io": { "command": "npx", "args": ["-y", "mcp-remote", "https://apis.io/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://apis.io/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
