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 sairam0424 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

Trelix is a local MCP server that gives an AI assistant semantic code search across a codebase, combining BM25 and vector search with call-graph analysis over…

What you can do: Search code semantically, combining keyword (BM25) and vector retrieval
Trace relationships between functions through call-graph analysis
Work across codebases in more than 20 programming languages
Run entirely as a local process on the user's machine
When to use it: Useful when an assistant needs to find relevant code in a larger or unfamiliar repository, or to follow how functions call each other, rather than relying on plain text matching.
Requirements: Runs as a local stdio process installed from the PyPI package trelix-mcp, so a Python environment is needed. No authentication, environment variables or headers are declared. Desktop only; not available as a web executable.

Before you install

The server indexes and reads source code from the local machine, so point it only at repositories you are comfortable having processed. No credentials or write actions are declared, but the tool list is not published, so review what it exposes before use.

Installation

In SourceWeft

Open trelix 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.

Tools

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the package did not install.

Score

25% 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.

Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
Tools listed15 pts
Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
