Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Manage IBM Watson Orchestrate tools, agents, connections from Cursor, Copilot, Claude.
These three are never merged into one score: opinions, measurements and popularity are different things.

Version 1.0.4 · Author Markus van Kempen · Date 2026-02-20
MCP server for IBM Watson Orchestrate (WXO). Manage tools, agents, connections, flows, and execute tools from Cursor, VS Code Copilot, Claude Desktop, Antigravity, Windsurf, or the WxO Builder extension.

This package has a dual role:
┌─────────────────────────────────┐ MCP protocol ┌──────────────────────────┐ HTTP (REST API) ┌─────────────────────────┐
│ MCP Client │ ◄──────────────────► │ WXO Builder MCP Server │ ───────────────────► │ Watson Orchestrate │ │ (Cursor, Claude Desktop, │ tool calls │ (this package) │ /v1/orchestrate/* │ instance │ │ Copilot, Antigravity, etc.) │ │ │ │ (your WO cloud/hosted) │ └─────────────────────────────────┘ └──────────────────────────┘ └─────────────────────────┘
The MCP server exposes tools that proxy operations to Watson Orchestrate. When you invoke a tool (e.g. list_skills, invoke_agent), the server forwards the request to the Watson Orchestrate API and returns the result.
The WxO Builder extension and this MCP Server work together to create and administer Watson Orchestrate directly from your IDE. Use the extension for visual editing and the MCP server for AI-powered workflows (Cursor, Claude Desktop, etc.).

The extension provides visual tool creation, drag-and-drop agent editing, and local/remote testing. The MCP server exposes the same Watson Orchestrate capabilities to AI assistants in Cursor, Claude Desktop, Antigravity, Windsurf, and VS Code Copilot.
Cursor Deep Link (use this so the install dialog shows "WxO Builder MCP Server"):

When WO_AGENT_IDs (comma-separated list) or WO_AGENT_ID is set, agent-based tools use the first ID as default when the user does not specify an agent.
Short description (≤100 chars):
Manage Watson Orchestrate tools, agents, connections. Pair with WxO Builder extension.
Longer description:
Manage IBM Watson Orchestrate (WXO) tools, agents, connections, and flows from Cursor, Copilot, or Claude. Best used with the WxO Builder VS Code extension for a full IDE experience: visual tool creation, drag-and-drop agents, and local/remote testing.

WO_INSTANCE_URL=https:// .orchestrate.ibm.com

When WO_AGENT_IDs (comma-separated) or WO_AGENT_ID is set, tools use the first ID as default when the user does not specify an agent.
npx so you never reference .js paths. Example for Cursor (.cursor/mcp.json):{
"mcpServers": { "watsonx": { "command": "npx", "args": ["-y", "wxo-builder-mcp-server"], "env": { "WO_API_KEY": "your-api-key", "WO_INSTANCE_URL": "https://xxx.orchestrate.ibm.com" } } } }
VS Code Copilot uses servers instead of mcpServers; same command and args:
{
"servers": { "watsonx": { "type": "stdio", "command": "npx", "args": ["-y", "wxo-builder-mcp-server"], "env": { "WO_API_KEY": "...", "WO_INSTANCE_URL": "https://...orchestrate.ibm.com" } } } }
