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, which broke the pydantic-ai build job on every PR regardless of what it changed. 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. - slack-bolt, slack-cli-hooks: range -> == - pydantic-ai, openai-agents: unpinned -> == - claude-agent-sdk, aiohttp: >= -> == - pytest, pytest-asyncio: unpinned -> == - ruff: 0.15.17 -> 0.15.19

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), which broke thebuild (pydantic-ai)job on every open PR — including ones that did not touch pydantic-ai.==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.ruff0.15.17 → 0.15.19,slack-bolt/slack-cli-hooks/claude-agent-sdk/aiohttpranges → exact,pytest/pytest-asyncio/openai-agentsunpinned → exact.Testing
requirements.txtand runpytest— all three pass (6/6 each).python -c "from pydantic_ai.mcp import MCPServerStreamableHTTP"succeeds under the pinnedpydantic-ai==1.107.0.ruff check .in each variant with 0.15.19 — all clean.
