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 silex-tec 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

Silex is a local MCP server that reconstructs a codebase's architecture, dependencies, workflows and business rules and serves that understanding to AI coding.

What you can do: Scan a local codebase across languages such as C#, JS/TS, Java, PHP, COBOL and VB to recover its architecture and dependencies. Map the system's communities and classify vendor or generated code out of the way. Surface workflows and business rules, with each claim anchored to a file and line and a verified quote. Flag unknown territory where nothing can be proven instead of guessing. Produce a shareable evidence report.
When to use it: Useful when an assistant must understand an unfamiliar or legacy codebase before changing it, and you want findings backed by file-and-line evidence rather than inference. Suited to local, privacy-sensitive work where code should not leave the machine.
Requirements: Runs as a local stdio process on the desktop. Needs Python 3.10 or later and the silex-archaeology package installed from PyPI (or a release wheel), then configured in an MCP client with the silex-mcp-server command and serve --stdio arguments. No account, card or API key is required.

Before you install

The README states code stays local with no telemetry, but the engine is proprietary and the repository only hosts distribution and documentation. The free tier is limited; team workspaces, deep visualization and refactoring trust contracts are listed as a coming Pro tier. Verify the package source before installing.

Installation

In SourceWeft

Open Silex 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.

README

Silex — evidence-based code archaeology

Understand the codebase before changing the code.

Silex reconstructs architecture, dependencies, workflows and business rules from your source code — and serves that understanding to your AI coding agents via MCP. Every claim is anchored to file:line with a verified quote. What Silex can't prove, it tells you.

Local-first. Your code never leaves your machine. No account, no card, no telemetry.

Install (free tier)

Until the PyPI release lands you can install the wheel from Releases: pip install https://github.com/silex-tec/silex/releases/latest/download/silex_archaeology-py3-none-any.whl

Connect it to your MCP client (Claude Code, Cursor, Claude Desktop, Windsurf, Cline, Continue, Zed) — stdio config:

json

{  "mcpServers": {    "silex": { "command": "silex-mcp-server", "args": ["serve", "--stdio"] }  }}

{  "mcpServers": {    "silex": { "command": "silex-mcp-server", "args": ["serve", "--stdio"] }  }}

Full install guide (Windows/PowerShell notes included): https://silex.tec.br/docs/

Try it on a real codebase

Clone Microsoft's eShop (MIT) and point a scan at it — the Concepts page shows the community graph, the recovered order state machine and anchored findings from that exact scan, so you can compare your output against a published reference.

What you get (free)

Local MCP server, full codebase scan (C#, JS/TS, Java, PHP, COBOL, VB…)
Community map — the real shape of the system, vendor/generated classified out of the way by default
Evidence anchored to file:line, confidence with provenance
Unknown-territory detection: what can't be proven is flagged, not guessed
Shareable evidence report
Works with the AI seat you already pay for

Pro tier (team workspaces, deep architecture visualization, refactoring trust contracts): coming soon — join the waitlist.

Bug reports and field feedback are welcome in Issues. The engine is proprietary; this repository hosts distribution, documentation and the public roadmap conversation.

Score

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.
