Mcp Scripts

parcadei/continuous-claude-v3

This is a style guide for writing Python scripts that interact with MCP servers through Claude's runtime. It enforces a clean pattern: use argparse for parameters, call tools via `call_mcp_tool("server__tool", params)`, and print to stdout. The double underscore naming convention for tools is specific and non-negotiable. The most practical bit is the hard rule against editing scripts to change parameters, which will save you from cluttering your git history with parameter tweaks. If you're building scripts that Claude will invoke to interact with MCP tools, these conventions keep things consistent and testable via the harness runner.

MCP Script Rules

When working with files in scripts/:

DO

  • Use CLI arguments for all parameters (argparse)
  • Include USAGE docstring at top of file
  • Use call_mcp_tool("server__tool", params) pattern
  • Handle errors gracefully with informative messages
  • Print results to stdout for Claude to process

DON'T

  • Hardcode parameters in the script
  • Edit scripts to change parameters (use CLI args instead)
  • Import from servers/ directly (use runtime.mcp_client)

Tool Naming

Tool IDs use double underscore: serverName__toolName

Examples:

  • morph__warpgrep_codebase_search
  • ast-grep__ast_grep
  • perplexity__perplexity_ask

Testing

Test with: uv run python -m runtime.harness scripts/<script>.py --help
