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

Programmatic (Batch/Parallel)
For batch operations or complex logic, use the API module:
import { callTool, listTools } from './scripts/api.mjs';
const tools = await listTools();
console.log(tools.map(t => ({ name: t.name, params: Object.keys(t.inputSchema?.properties || {}) })));
const result = await callTool('toolName', { });
const results = await Promise.all([
callTool('tool1', { }),
callTool('tool2', { }),
]);
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)
Error Handling
If a tool call fails (e.g., "method not found", parameter changes):
- Try to complete the task using other available tools
- Inform user: "This skill may be outdated - MCP server API has changed"
- User needs to run mcp-skill-generator to update this skill
Do not retry failed calls repeatedly - prioritize finding alternatives.
