Vectr MCP Server

Version 1.12.0 · Last updated 2026-09-03 · CHANGELOG Your AI code editor pays for the same knowledge twice. It re-reads files it read yesterday, re-greps symbols it already found, and loses the exact signature it discovered at turn 5 the moment the conversation is compacted. It runs locally over stdio via the published package.

People who work with code search, developer tools and embeddings and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Vectr

before you install - you'll need

Set ANTHROPIC_BASE_URL before connecting.

Claude Code

claude mcp add swapnanil-vectr -- uvx vectr

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "swapnanil-vectr": {
      "command": "uvx",
      "args": [
        "vectr"
      ]
    }
  }
}

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.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

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

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

06 · Vectr FAQ

What is Vectr?

Is Vectr still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-06 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Vectr?

Run `uvx vectr`. The README documents one environment variable (ANTHROPIC_BASE_URL) to set first. Set ANTHROPIC_BASE_URL before connecting. You can also paste the ready-made client config above.

Does Vectr run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
