proxy

proxy

Proxy tool enables dynamic access to MCP servers by listing, retrieving detailed info, or calling tools, resources, and prompts. Provides a unified interface with JSON-encoded results for client interpretation.

Instructions

Main proxy tool for dynamic access to mounted MCP servers.

This tool provides a unified interface for:

Listing available tools, resources, or prompts across servers
Getting detailed info about specific capabilities
Calling tools, reading resources, or getting prompts

Annotations are used to provide rich type information for results, which can generally be expected to ultimately include JSON-encoded EmbeddedResource results that can be interpreted by the client.

Input Schema

`filter_server`	No	Filter results by server name prefix (for 'list' action only)
`limit`	No	Maximum number of items to return (for 'list' action only). Default: 100
`offset`	No	Number of items to skip (for 'list' action only). Default: 0
`path`	No	Name or URI of the specific tool/resource/prompt (with FastMCP prefixing). Not allowed for 'list' and 'info' actions.
