connect-tools-and-mcp

Giving crewAI agents tools and MCP servers on crewai 1.15.x: custom BaseTool with args_schema and @tool, which crewai_tools names really exist, tool caching, max_usage_count, ToolFailure, Agent(mcps=[...]) string and MCPServerStdio/HTTP/SSE forms, rewritten MCP tool names, MCPServerAdapter, timeouts, and what works on a hosted deployment. Use when writing or debugging a tool or MCP connection, when you see 'cannot import name BaseTool from crewai_tools', 'You are missing the mcp package', 'MCPConnectionError', 'Operation timed out after 30 seconds', 'reached its usage limit', 'Invalid MCP reference', 'Anthropic function name ... must start with a letter', an agent that never calls an MCP tool, mcps=[...] that yields no tools (for example an https:// string under akickoff or on CrewAI AMP), or a stdio MCP server that works locally but not after deploy.
