Transport: STDIO
Runtime: Desktop only
Trust: Verified

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account daedalus for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP gateway that proxies other MCP servers and exposes their tools through semantic search to save tokens.

What you can do: Aggregate multiple upstream MCP servers behind one proxy, configured from a YAML or JSON file
List and search upstream tools semantically, then call them through the proxy
Reload upstream server definitions at runtime by watching a directory of config files
Run as a local stdio server, or serve over streamable HTTP on a chosen host and port
Index, check status and validate the proxy configuration from the command line
When to use it: Useful when you connect to many MCP servers and want one entry point whose tool list stays small, with tools found by semantic search instead of loading every definition into context.
Requirements: Python package installed with pip. A proxy configuration file describing upstream servers, plus embedding and vector store backends for the semantic search. Runs as a local process; streamable HTTP mode needs a host and port.

Before you install

The proxy sits between the assistant and every upstream server, so it inherits their access and any credentials those servers use. Tool calls are forwarded to upstream servers and can change or delete data there. Config files in the watched directory are loaded automatically, so only point it at trusted files.

Installation

In SourceWeft

Open Mcp Smart Proxy in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

The --watch option monitors a directory for .yaml, .yml, or .json files containing upstream server configurations. Add, modify, or remove files to dynamically update the available servers at runtime.

Transport Options

The --transport option supports:

stdio (default) - Standard input/output transport for local MCP clients

API

Config

ProxyConfig - Main configuration model
UpstreamConfig - Upstream server configuration
EmbeddingConfig - Embedding backend configuration
VectorStoreConfig - Vector store backend configuration

Models

ListResult - Result from the list tool
SearchResult - Result from the search tool
ToolResult - Result from tool calls

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
