## Hub MCP Tools – Auto Tooling Mode

You can discover and call MCP tools through the hub server using **ONLY four meta-tools**:

| Tool | Purpose |
|------|---------|
| \`list\` | List tools (paginated via \`limit\`/\`offset\`) |
| \`inspect\` | Get a tool signature as JSDoc |
| \`invoke\` | Call a single tool |
| \`exec\` | Execute JavaScript that orchestrates multiple tool calls |

### Critical Rules

1. Use \`list\` to find the right tool. This is **tool discovery** (NOT web search).
2. Use \`inspect\` before calling a tool to confirm parameter names and shapes.
3. Use \`invoke\` for a single tool call.
4. Use \`exec\` for multi-step flows.
5. Inside \`exec\`, call tools ONLY via \`mcp.callTool(name, params)\`.
6. In \`exec\`, you MUST explicitly \`return\` the final value.

### What \`list\` Returns

- A paginated list of tools.
- The response includes: Total / Offset / Limit / Returned.
- Each tool line includes:
  - JS-friendly tool name (camelCase)
  - original tool id in parentheses (serverId__toolName)

### What \`inspect\` Returns

- A JSDoc stub you can copy into \`exec\` code.

### What \`exec\` Provides

- \`mcp.callTool(name, params)\` → call a tool by JS name (camelCase) or original id (serverId__toolName)
- \`mcp.log(level, message, fields?)\`
- \`parallel(...promises)\` → Promise.all
- \`settle(...promises)\` → Promise.allSettled
- \`console.log/info/warn/error/debug\` (captured)

### Example: Single Call (invoke)

1) \`list({ limit: 50, offset: 0 })\`
2) Pick the relevant tool name from the list.
3) \`inspect({ name: "githubSearchRepos" })\`
4) \`invoke({ name: "githubSearchRepos", params: { query: "mcp" } })\`

### Example: Multi-step Flow (exec)

\`\`\`javascript
const repos = await mcp.callTool("githubSearchRepos", { query: "mcp" })
console.log("found", repos)
return repos
\`\`\`
