Coalent MCP Server

Real-time, provenance-invalidated context for AI agents & RAG. Build understanding once. Reuse it everywhere. Keep it fresh - automatically. It runs locally over stdio via the published package.

People who work with Coalent and Openai and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Coalent

before you install - you'll need

Set COALENT_MCP_TOKEN, OPENAI_API_KEY before connecting.

Claude Code

claude mcp add vectorlink-labs-coalent -- uvx coalent

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vectorlink-labs-coalent": {
      "command": "uvx",
      "args": [
        "coalent"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

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 Apache-2.0 - declared in the repository

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

registry registry publisher io.github.nisarg-pujara-vectorlink is not the repo owner (vectorlink-labs) - the registry entry was published by someone else

The cache now heals itself from its own read traffic. When a read fails, your agent calls repair(read_id) and the cache re-extracts the facts its build missed - permanently: the claims join the store with per-claim…

v0.6.1 · 2026-08-05

Coalent now mounts directly into Claude Code, Cursor, and any MCP client - and wraps any LangChain vectorstore. The library itself is unchanged: 0.6.1 is additive on top of 0.6.0. · > Installing today gets you 0.6.2…

v0.6.0 · 2026-08-03

The claim-pool-first read path ships, opt-in, with a default-OFF behavioral stack. A v0.5 user who upgrades and touches nothing gets v0.5 behavior - the default path is byte-stable, modulo the bugfix below. · bash…

06 · Coalent FAQ

What is Coalent?

Real-time, provenance-invalidated context for AI agents & RAG. Build understanding once. Reuse it everywhere. Keep it fresh - automatically. It runs locally over stdio via the published package.

Is Coalent still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-17 and it shipped 6 releases in the last 90 days. We re-verify nightly.

How do I install Coalent?

Run `uvx coalent`. The README documents 2 environment variables (COALENT_MCP_TOKEN, OPENAI_API_KEY) to set first. Set COALENT_MCP_TOKEN, OPENAI_API_KEY before connecting. You can also paste the ready-made client config above.

Does Coalent 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.
