# List available tools and their schemas
node ./scripts/mcp-caller.mjs list
# Then check tools/<tool-name>.md for parameter details
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"}'
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 toollistTools() - List available tools (includes inputSchema with parameter info)readResource(uri) - Read a resourcelistResources() - List resourcesgetPrompt(name, args) - Get a promptlistPrompts() - List promptsclose() - Close connection (optional cleanup)If a tool call fails (e.g., "method not found", parameter changes):
Do not retry failed calls repeatedly - prioritize finding alternatives.
