Bumps fastmcp from 2.13.1 to 2.14.3.

Release notes

Sourced from fastmcp's releases.

v2.14.3: Time After Timeout

This patch release fixes an HTTP transport timeout bug where connections were defaulting to 5 seconds instead of respecting MCP's 30-second default, causing premature timeouts for slower operations. Also includes OAuth token storage fixes, Redis key isolation for ACL compliance, and improved ContextVar propagation for ASGI-mounted servers. Plus, the CLI will now nudge you when updates are available (you're welcome, future you).

v2.14.2: Port Authority

FastMCP 2.14.2 brings a wave of community contributions safely into the 2.x line. A variety of important fixes backported from 3.0 work improve OpenAPI 3.1 compatibility, MCP spec compliance for output schemas and elicitation, and correct a subtle base_url fallback issue. The CLI now gently reminds you that FastMCP 3.0 is on the horizon.

v2.14.1: 'Tis a Gift to Be Sample

FastMCP 2.14.1 adds support for sampling with tools (SEP-1577). This exciting new feature lets servers pass tools to ctx.sample(), enabling agentic workflows where the server borrows the client's LLM and controls tool execution automatically. Pass any callable as a tool and FastMCP handles the loop: calling the LLM, executing tools, and feeding results back until a final response is produced. For fine-grained control, ctx.sample_step() makes a single LLM call and returns a SampleStep, letting you inspect tool calls, add custom logic, or build your own execution loop. Structured output via result_type returns validated Pydantic models instead of raw text. This release also adds AnthropicSamplingHandler alongside the existing OpenAI handler (newly promoted out of the experimental module), so clients and servers can provide sampling capability across major providers with ease.
