Add list_resources, list_prompts, and get_prompt methods to Context

[strawgate]

Enhancement

Adds list_resources(), list_prompts(), and get_prompt() methods to the Context class to improve API consistency.

Previously, the Context object had read_resource() but lacked list_resources() and list_prompts() methods. This created an inconsistency where middleware/tools needed to create temporary Client instances to list resources/prompts but could use context methods to read/get them.

Changes

• Added Context.list_resources() to list all available resources
• Added Context.list_prompts() to list all available prompts
• Added Context.get_prompt() to get a specific prompt with arguments
• Updated ToolInjectionMiddleware to use new Context methods instead of creating temporary Client instances
• Removed unused Client and FastMCPTransport imports

These methods follow the same pattern as read_resource() and delegate to the FastMCP server's internal MCP methods.

Example

@server.tool
async def my_tool(ctx: Context) -> str:
    # List available resources
    resources = await ctx.list_resources()
    
    # List available prompts
    prompts = await ctx.list_prompts()
    
    # Get a specific prompt
    result = await ctx.get_prompt("my_prompt", {"arg": "value"})
    
    return "Done"

Fixes #2245

Pull Request Overview

This PR adds three new methods to the Context class (list_resources(), list_prompts(), and get_prompt()) to improve API consistency and eliminate the need for middleware to create temporary Client instances. The change streamlines the API by allowing all resource and prompt operations to be performed directly through the Context object.

Key changes:

• Added list_resources(), list_prompts(), and get_prompt() methods to the Context class
• Updated ToolInjectionMiddleware to use the new Context methods instead of creating temporary Client instances
• Removed unused Client and FastMCPTransport imports from the middleware

/marvin the ctx.fastmcp property can't return none anyway

Task completed

• Review the code to find unnecessary None checks for ctx.fastmcp
• Remove unnecessary None checks
• Run validation (pre-commit, tests)
• Commit and push changes

Removed unnecessary None checks from these methods:

• list_resources()
• list_prompts()
• get_prompt()
• read_resource()

The fastmcp property raises RuntimeError if the FastMCP instance is None, so these checks were redundant.

All tests and linting passed. Changes have been committed and pushed.
