AgentAPIList MCP server

A remote Model Context Protocol server that exposes this site’s data to agents. It has eight tools: estimate_cost and compare_apis work out monthly cost from requests and tokens using the same price table as the cost calculator; get_api and list_apis return dated, source-linked API facts; list_agent_tools, get_agent_tool and compare_agent_tools cover the free agent tools listed here (filter by free, no key, MCP and commercial use); search looks across both. It is stateless, needs no key, and returns plain JSON over Streamable HTTP. This is our own tool, so read the conflict-of-interest note and check the alternatives.

Prompt to give your agent

You have the MCP server "agentapilist". Before recommending an AI API or a free agent tool, call search or list_agent_tools to find candidates and estimate_cost for my volume (I send about 200,000 requests a month, 800 input and 50 output tokens each). Quote each price with its price_date and source_url, say when an API is listed as not comparable, and remind me that AgentAPIList runs this server, so check the vendor page before I commit.
