Basic setup for an MCP server with one tool.

from dcc_mcp_core import MCPServer, create_context # Create an MCP server instance server = MCPServer(name="example-server") # Register a simple tool @server.tool def greet(name: str) -> str: return f"Hello, {name}!" # Create context and run context = create_context(server) context.run()

Debug

Known issues

breakingIn v0.18.0, `create_context` was moved to top-level. Importing from `dcc_mcp_core.context` will fail.

fix

Use `from dcc_mcp_core import create_context`

affects: >=0.18.0

gotchaPackage name uses underscores, not dots. `dcc-mcp-core` is the PyPI name, but import is `dcc_mcp_core`.

fix

Always use `import dcc_mcp_core`

affects: all

deprecatedThe `MCPClient` class signature changed in v0.17.0; the `host` parameter is now `server_url`. Old code will raise TypeError.

fix

Use `MCPClient(server_url='ws://...')` instead of `MCPClient(host='...')`

affects: >=0.17.0

breakingPython 3.7 support dropped in v0.19.0 (future). Current version 0.18.9 still supports 3.7, but plan to upgrade.

fix

Use Python 3.8+ for future versions

affects: >=0.19.0
