chore(deps): pin all Python dependencies to exact versions#130
Merged
Conversation
Every variant declared loose or unpinned dependencies (bare pydantic-ai/openai-agents, >= and < ranges), so CI resolved the latest release at run time. pydantic-ai 2.0.0 removed MCPServerStreamableHTTP (now unified under MCPToolset), which would break the pydantic-ai build job on any newly triggered run. Pin every dependency to an exact == version across all three variants' requirements.txt and pyproject.toml. pydantic-ai is pinned to 1.107.0, the last 1.x release that still exports MCPServerStreamableHTTP; migrating to the new MCPToolset API is left for a follow-up. Mirrors the same fix applied to bolt-python-starter-agent.

This pull request pins every Python dependency across all three agent variants to an exact
==version.Summary
pydantic-ai 2.0.0removedMCPServerStreamableHTTP(now unified underMCPToolset) — under the barepydantic-ai[...]spec, any newly triggeredbuild (pydantic-ai)run would fail on import. (This already broke CI on the siblingbolt-python-starter-agent.)==in each variant'srequirements.txtandpyproject.tomlso this cannot recur; Dependabot now drives future bumps.pydantic-aiis pinned to1.107.0, the last 1.x release that still exportsMCPServerStreamableHTTP. Migrating to the newMCPToolsetAPI is left as a follow-up.bolt-python-starter-agent.Testing
requirements.txt, thenpip install -e ".[test]"and runpytest— all three pass (9/9 each).python -c "from pydantic_ai.mcp import MCPServerStreamableHTTP"succeeds under the pinnedpydantic-ai==1.107.0.
