ABLESTACK MOLD MCP Server

Instructions

Implementation Reference

• src/app/tools.js:73-77 (handler)

  The handler function for the 'mold_call' tool. It flattens the input parameters and calls the generic callApi function to execute the MOLD API request, returning the JSON response as text.
  async ({ command, params }) => { const flat = flattenParamsForMold(params ?? {}); const data = await callApi(command, flat); return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] }; }
• src/app/tools.js:50-71 (schema)

  Zod input schema for the 'mold_call' tool, defining 'command' as string and optional 'params' as record of string keys to union of primitives or nested records.
  inputSchema: { command: z.string(), params: z .record( z.string(), z.union([ z.string(), z.number(), z.boolean(), z.record( z.string(), z.union([ z.string(), z.number(), z.boolean(), z.record(z.string(), z.union([z.string(), z.number(), z.boolean()])), ]) ), ]) ) .optional(), },
• src/app/tools.js:45-78 (registration)

  Full registration of the 'mold_call' tool in registerCoreTools, specifying name, metadata, input schema, and handler function.
  server.registerTool( "mold_call", { title: "MOLD API 호출(범용)", description: "임의의 MOLD API 명령을 호출합니다. (command + params)", inputSchema: { command: z.string(), params: z .record( z.string(), z.union([ z.string(), z.number(), z.boolean(), z.record( z.string(), z.union([ z.string(), z.number(), z.boolean(), z.record(z.string(), z.union([z.string(), z.number(), z.boolean()])), ]) ), ]) ) .optional(), }, }, async ({ command, params }) => { const flat = flattenParamsForMold(params ?? {}); const data = await callApi(command, flat); return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] }; } );
• src/api/mold.js:39-47 (helper)

  Core helper function called by the handler to perform the actual signed API request to MOLD using fetch.
  export async function callApi(command, params = {}) { const url = buildSignedUrl({ command, ...params }); const res = await fetch(url); if (!res.ok) { const text = await res.text(); throw new Error(`HTTP ${res.status}: ${text} from: ${url} and params: ${JSON.stringify(params, null, 2)}`); } return res.json(); }
• src/util/params.js:7-76 (helper)

  Helper function to flatten nested parameters into flat object with bracket and dot notation suitable for MOLD API.
  export function flattenParamsForMold(params = {}) { const out = {}; const put = (k, v) => { if (v === undefined || v === null) return; out[k] = String(v); }; const walkNested = (val, base) => { if (val === undefined || val === null) return; if (Array.isArray(val)) { if (val.length && typeof val[0] === "object") { val.forEach((item, i) => walkNested(item, `${base}[${i}]`)); } else { put(base, val.map((x) => String(x)).join(",")); } return; } if (typeof val === "object") { for (const [sk, sv] of Object.entries(val)) { if (sv === undefined || sv === null) continue; if (typeof sv === "object" && !Array.isArray(sv)) { walkNested(sv, `${base}.${sk}`); } else { put(`${base}.${sk}`, sv); } } return; } put(base, val); }; for (const [key, val] of Object.entries(params)) { if (val === undefined || val === null) continue; if (/[.\[]/.test(key)) { put(key, val); continue; } if (Array.isArray(val)) { if (val.length && typeof val[0] === "object") { val.forEach((item, i) => { for (const [sk, sv] of Object.entries(item || {})) { if (sv === undefined || sv === null) continue; if (typeof sv === "object" && !Array.isArray(sv)) { walkNested(sv, `${key}[${i}].${sk}`); } else { put(`${key}[${i}].${sk}`, sv); } } }); } else { put(key, val.map((x) => String(x)).join(",")); } continue; } if (typeof val === "object") { for (const [sk, sv] of Object.entries(val)) { if (sv === undefined || sv === null) continue; if (typeof sv === "object" && !Array.isArray(sv)) { walkNested(sv, `${key}[0].${sk}`); } else { put(`${key}[0].${sk}`, sv); } } continue; } put(key, val); } return out; }
