Provider Packages with Copilot: Quick Reference

One page for the contributor workflow in SETUP_GUIDE.md.

Start

cd python/examples/mcp && uv sync && uv run python src/server_http.py   # port 3101
curl -s http://localhost:3101/health

.vscode/mcp.json:

{ "servers": { "matimo-python-mcp-server": { "type": "http", "url": "http://localhost:3101/mcp" } } }

In Copilot Chat, choose Matimo Tool Creator and describe the provider and its API docs.

MCP Tools the Agent Uses

Tool	Input	Asks you first?
matimo_validate_tool	yaml_content	No
matimo_validate_skill	name, skills_dir	No
matimo_list_skills, matimo_get_skill	name	No
web	URL	No
search, read	query, directory / filePath	Yes
execute	command, optional args, cwd, timeout, shell	Yes, and always when shell is set
edit	filePath, operation, content	Yes
matimo_create_skill	name, content, target_dir	Yes
matimo_reload_tools	n/a	Yes

matimo_create_tool and matimo_approve_tool are for agents creating their own runtime tools, not for provider packages.

HTTP tool YAML is identical in both SDKs.

Tool YAML Essentials

name: provider_action              # snake_case, unique
description: From the API docs
version: '1.0.0'                   # leave status unset
parameters:
  item_id: { type: string, required: true, description: Item ID }
execution:
  type: http
  method: GET
  url: 'https://api.provider.com/v1/items/{item_id}'
  headers:
    Authorization: 'Bearer {PROVIDER_API_KEY}'   # MATIMO_PROVIDER_API_KEY or PROVIDER_API_KEY
  timeout: 15000
requires_approval: true            # required for DELETE / destructive calls

Checks

cd typescript && pnpm validate-tools && pnpm lint && pnpm test -- packages/<provider>
cd python && uv run ruff check packages/<provider> && uv run pytest packages/<provider>

Quick Fixes

Problem	Fix
Port in use	MATIMO_SERVER_PORT=3102
No tools in VS Code	URL must end in /mcp; check /health
Agent can’t reach a tool	Server name must be matimo-python-mcp-server
Approval error instead of a prompt	Use a client with MCP elicitation support
New tool not visible	Restart the server
Tool loads in Python only	Remove status: stable
