Selvedge MCP Server

Persistent decision memory for AI coding agents. Selvedge records why code changed, which approaches were rejected, and when decisions deserve another look, so future sessions can retrieve that context before editing. Query a function, database column, API route or dependency instead of reconstructing its history from an old conversation. It runs locally over stdio via the published package.

People who work with agent trace, ai code provenance and codebase change tracking and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Selvedge

Claude Code

claude mcp add masondelan-selvedge -- uvx selvedge

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "masondelan-selvedge": {
      "command": "uvx",
      "args": [
        "selvedge"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

license MIT - declared in the repository

pypi package selvedge - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.masondelan is GitHub-verified and matches the repo owner
