MCP Tools

Nemo provides three MCP tools for discovering and invoking capabilities:

  • search_tools: Search for MCP tools and agent skills by keyword. Returns compact results by default (tool name, server, title). Set detail='full' to include descriptions and input schemas. Use source to filter by type (all, mcp, skills).
  • call_tool: Call a tool on a remote MCP server by specifying the endpoint, tool name, and arguments. Response is truncated to maxResponseChars (default 10000). Tracks latency and logs usage.
  • get_skill: Get full instructions for an agent skill. Returns the complete SKILL.md content, install command, and metadata. Use after search_tools to get detailed skill instructions.

HTTP API

Nemo also exposes REST API endpoints for direct access:

Search

curl "https://nemo.25chenghua.workers.dev/api/search?q=QUERY&limit=5&detail=compact&source=all"

Each result has a type field: "mcp_tool" or "skill".

Get Skill Instructions

curl "https://nemo.25chenghua.workers.dev/api/skill/SKILL_NAME?repo=owner/repo"

Returns the complete instructions, install command, and metadata.

Call a Remote MCP Tool

curl -X POST "https://nemo.25chenghua.workers.dev/api/call" \
  -H "Content-Type: application/json" \
  -d '{"endpoint": "SERVER_URL", "tool": "TOOL_NAME", "args": {}}'

Use the serverEndpoint and toolName from search results.

Workflow

  1. Search: curl ".../api/search?q=file+conversion"
  2. If result is type: "skill" → get instructions: curl ".../api/skill/SKILL_NAME" → follow them
  3. If result is type: "mcp_tool" → call it: POST .../api/call with endpoint, tool, args

Useful for AI agents that need to discover and invoke tools dynamically across a distributed network of MCP servers and agent skills.
