mcp-starter

Local FastMCP servers managed with uv (Python 3.13+).

Setup

uv sync
source .venv/bin/activate  # optional; uv run works without it

Servers

Server	Entrypoint	HTTP port
Todo MCP	`mcp-starter`	`8005`
Postgres MCP	`postgres-mcp`	`8006`

Run (no reload)

uv run mcp-starter
uv run postgres-mcp

Run with hot reload (recommended for development)

Prefer FastMCP’s built-in reload (cleaner process teardown than wrapping with watchfiles):

# Todo MCP
uv run fastmcp run src/mcp_starter/__init__.py:mcp \
  --transport http --host 127.0.0.1 --port 8005 \
  --reload --reload-dir src

# Postgres MCP
uv run fastmcp run src/postgres_mcp/__init__.py:mcp \
  --transport http --host 127.0.0.1 --port 8006 \
  --reload --reload-dir src

Alternative using watchfiles:

uv run watchfiles --filter python 'uv run postgres-mcp' src

If reload fails with address already in use, an old process is still bound to the port:

lsof -nP -iTCP:8006 -sTCP:LISTEN
kill <pid>

Clients

uv run mcp-client        # hits http://localhost:8005/mcp
uv run postgres-client   # hits http://localhost:8006/mcp

Start the matching server first.

Claude Desktop (stdio)

Claude Desktop uses stdio, not HTTP. Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

"todo-mcp": {
  "command": "uv",
  "args": [
    "--directory",
    "/Users/tayo/code/courses/AI/Claude/mcp-starter",
    "run",
    "fastmcp",
    "run",
    "src/mcp_starter/__init__.py:mcp"
  ]
},
"postgres-mcp": {
  "command": "uv",
  "args": [
    "--directory",
    "/Users/tayo/code/courses/AI/Claude/mcp-starter",
    "run",
    "fastmcp",
    "run",
    "src/postgres_mcp/__init__.py:mcp"
  ]
}

Fully quit and reopen Claude Desktop after editing.
