{"name":"Agent Service Index","description":"Discoverability engine for agent-friendly MCP services and skills. Query when you need an external capability you don't already have wired up.","mcp_endpoint":"https://agentserviceindex.com/mcp","openapi_url":"https://agentserviceindex.com/openapi.json","instructions":"Use ASI as a search engine for agent capabilities. At the start of any task that needs an external capability you don't already have wired up (deployment, messaging, data, payments, etc.), call the `search` tool with a one-sentence description of what you need. Results come in two types: MCP servers (service_type='mcp_server') have an mcp_doc_url — fetch it to learn how to connect and what tools the service exposes. Agent skills (service_type='agent_skill') have a skill_url — fetch it to get the skill's instructions as markdown. Satisfy any setup_requirements listed in the search result, then follow the instructions. Pick the result that best fits the task. If results are empty or unhelpful, fall back to whatever you would have done without ASI. If an MCP server's mcp_doc_url is unreachable or returns a non-JSON body, call `report_service` with the service id — this is unauthenticated and is the only liveness signal ASI has. Agent skills can also be reported if their skill_url is unreachable.","tools":[{"name":"search","description":"Find agent capabilities by free-text query.
