Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs a command on install [пакет] package.json:1
postinstall: node -e "import('./dist/postinstall.js').catch(()=>{})"

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add prism-coder -- npx -y prism-mcp-server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "prism-coder": {
      "args": [
        "-y",

      ],
      "command": "npx"
    }

  }
}

This one needs environment variables set before it will start: BRAVE_API_KEY (Brave Search API key for web search tools), GEMINI_API_KEY (Google Gemini API key for AI-powered summarization and embeddings), SUPABASE_URL (Supabase project URL for session memory and knowledge persistence), SUPABASE_KEY (Supabase service role key for database access), PRISM_USER_ID (User ID for multi-tenant row-level security isolation (defaults to 'default')), GCP_PROJECT_ID (Google Cloud project ID for Vertex AI Discovery Engine integration), VERTEX_LOCATION (Vertex AI location/region (defaults to 'global')), VERTEX_DATA_STORE_ID (Vertex AI Discovery Engine data store ID for enterprise search). The author declared them in the registry entry; get the values from the project itself.

Prism Coder — questions

Answers built from our own checks of this server.

Why is there no uptime for Prism Coder?
Prism Coder runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package prism-mcp-server was installed 1 739 times last week.
How do I connect Prism Coder?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls prism-mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Prism Coder?
The npm package prism-mcp-server was installed 1 739 times in the last week. Week over week that is +10%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Prism Coder open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript and 158 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
