What is python-sdk?

python-sdk helps connect external tools, services, or data sources to AI hosts that support MCP.
Best fit: Developers who need Claude, Cursor, Codex, or another MCP-capable AI host to call external tools safely.
Not for: Not for users who cannot change host configuration, grant tool permissions, or isolate network, file, and credential access.
Capability added to an AI workflow: MCP setup guidance, host configuration checks, tool permission boundaries, recovery steps, and acceptance checks
First safe verification step: Verify the MCP server command, permission scope, and rollback path in a non-primary host configuration first.
Verification state: source, Quick Start, and sandbox install checks are recorded as passed.
Top risk: The main risk is unclear tool, filesystem, network, or credential boundaries contaminating host configuration or exposing sensitive data.
Evidence base: https://github.com/modelcontextprotocol/python-sdk, https://github.com/modelcontextprotocol/python-sdk#readme, Human Manual, Pitfall Log
