See prompts.md for details.

Usage

Quick Start

⚠️ Before calling any tool, read its documentation in tools/ to get the exact parameter names.

# List available tools and their schemas
node ./scripts/mcp-caller.mjs list

# Then check tools/<tool-name>.md for parameter details

CLI (Single Call)

Run from this skill directory:

node ./scripts/mcp-caller.mjs call <tool> '<json-args>'
node ./scripts/mcp-caller.mjs resource <uri>
node ./scripts/mcp-caller.mjs prompt <name> '<json-args>'
node ./scripts/mcp-caller.mjs list

Example:

node ./scripts/mcp-caller.mjs call fetch '{"url": "https://example.com"}'

Programmatic (Batch/Parallel)

For batch operations or complex logic, use the API module:

// example.mjs - Run from this skill directory
import { callTool, listTools } from './scripts/api.mjs';

// First, check available tools and their schemas
const tools = await listTools();
console.log(tools.map(t => ({ name: t.name, params: Object.keys(t.inputSchema?.properties || {}) })));

// Then call with correct parameters (see tools/*.md for details)
const result = await callTool('toolName', { /* check tools/toolName.md for params */ });

// Parallel calls
const results = await Promise.all([
  callTool('tool1', { /* params from tools/tool1.md */ }),
  callTool('tool2', { /* params from tools/tool2.md */ }),
]);

console.log(JSON.stringify(results, null, 2));

Available API functions:

callTool(name, args) - Call a tool
listTools() - List available tools (includes inputSchema with parameter info)
readResource(uri) - Read a resource
listResources() - List resources
getPrompt(name, args) - Get a prompt
listPrompts() - List prompts
close() - Close connection (optional cleanup)
