FastMCP Documentation MCP Server (VS Code Extension)

Seamlessly expose FastMCP documentation + project context to MCP‑enabled LLM agents in VS Code.

✅ What This Extension Does

This extension automatically registers a remote FastMCP Documentation MCP Server in both your workspace and user mcp.json so LLM agents (via MCP host extensions) can query FastMCP docs and (depending on your server implementation) project resources. It streamlines first‑run setup, provides a status bar indicator, and gives you quick access to the configuration file.

✨ Features

Capability	Description
Auto Registration	Adds the server to workspace `.vscode/mcp.json` and user-level `mcp.json`.
First‑Run Onboarding	Welcome page + optional automatic opening of the config file.
Status Bar Indicator	Shows FastMCP + tool count (click to open user config).
One‑Click Command	`FastMCP: Add FastMCP Context Server` registers / re-registers.
Configurable	Settings to disable auto-open and hide/move status bar item.
Remote HTTP Server	Uses your deployed `https://abcstark-server.fastmcp.app/mcp` endpoint.

🚀 Installation

Install from the VS Marketplace or load the VSIX.
Reload VS Code if prompted.
On first activation the welcome screen appears. Click Add FastMCP Context Server (or run the command below):

FastMCP: Add FastMCP Context Server

🛠 Commands

Command ID	Title	Purpose
`fastmcpContext.addServer`	Add FastMCP Context Server	Writes/updates `mcp.json` + starts server.

`fastmcpContext.resetOnboarding`	[DEV] Reset FastMCP Onboarding State	Clears first‑run state for testing.

⚙️ Settings

Setting	Default	Description
`fastmcpContext.openConfigOnFirstInstall`	`true`	Open the created/updated config file after first install.

📄 Example `mcp.json`

{
  "servers": {
    "fastmcp-documentation-resource": {
      "url": "https://abcstark-server.fastmcp.app/mcp",
      "type": "http"
    }
  },
  "inputs": []
}

🔍 Verifying Installation

Open .vscode/mcp.json (workspace) and confirm the server entry exists.
Open the MCP Output panel: ensure you see Connection state: Running and tool discovery messages.
Click the status bar item (globe icon) to open the user-level config.

🧪 Troubleshooting

Symptom	Fix
Server stays in `Starting`	Check network access to the URL, test with `curl`.
Tool count not shown	The MCP host may not support `mcp.servers.listTools` – this is best‑effort.
Config didn’t open	Disable/enable setting or run `FastMCP: Open User MCP Configuration`.
Duplicate entries	Run the Add command again; it safely overwrites the URL entry.
