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": { "massive-com": { "url": "https://mcp.massive.com" } } }

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

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

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://mcp.massive.com \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools

search_endpoints — Search for API endpoints and built-in functions by natural language query. Returns titles, path patterns, and descriptions. detail can be "more" (query parameter docs) or "verbose" (full documentation); max_results limits results; scope="functions" discovers built-in analytics functions.
call_api — Call any Massive.com REST API endpoint. Supports storing results as an in-memory SQLite table (store_as) and applying post-processing functions (apply). Paginated responses include a next-page hint.
query_data — Run SQL against the in-memory SQLite database of stored results. Supports SHOW TABLES, DESCRIBE, DROP TABLE, CTEs, window functions; results can be post-processed with apply.

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.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
