Prism Coder

Claimed

by dcostenco

Persistent session memory for AI coding agents — local-first, with on-device inference, associative recall, and drift detection. Works with Claude Code, Cursor, and Codex.

Set up this server

01 / Choose your client

02 / Before you connect

The maintainer declares that no authentication is required.

Install the runtime required by the project and make it available to your client.

Project instructions

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: maintainer launch command

claude mcp add --transport stdio 'prism-coder' -- 'npx' '-y' 'prism-mcp-server'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.

Security profile

Exposure: Broad

Reaches into the environment, credential files or other agents' configuration.

What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.

  • Talks to external services14 places

    Makes outbound requests. The hosts are listed so you can see where data goes.

  • Sends conversation content outward1 places

    Logs or forwards prompts, messages or tool results to a service outside your machine.

  • Runs shell commands4 places

    Spawns processes on your machine. Expected for command, browser and build tools.

  • Loads code at runtime2 places

    Uses eval, dynamic imports or encoded payloads, which static review cannot fully follow.

  • Reads or writes other agents' configuration3 places

    Touches folders such as ~/.claude, ~/.codex or ~/.cursor, which hold settings and sometimes keys.

  • Contains instructions aimed at AI agents13 places

    Text in code or agent-facing files that steers a model. Worth reading before you trust it.

  • Passes model output on without checks2 places

    Model output reaches HTML, SQL or a shell without validation.

  • Runs unpinned packages at runtime18 places

    Executes npx or uvx without a version, so a compromised upstream release would run.

Not detected: reads environment variables in bulk, accesses credential files, uses elevated privileges, installs itself to run later, matches a known malicious pattern.

Dependencies with known advisories

None found in the lockfiles and manifests checked against OSV.dev.

Left out of the profile

25 pattern matches in documentation, configuration or CI files were recorded but are not part of the profile, because they do not run when the server does. The owner dashboard lists them.

FAQ

Questions about Prism Coder MCP Server

How do I connect Prism Coder MCP Server to Claude?
Run `claude mcp add prism-coder -- npx -y prism-mcp-server` in Claude Code, or add the same command and arguments under mcpServers in Cursor's mcp.json or Claude Desktop's claude_desktop_config.json, then restart the client. The blocks above are ready to paste.
Is Prism Coder MCP Server free?
The listed licence is Apache-2.0. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.
What can Prism Coder MCP Server do?
MCPVault has not yet recorded the tool list for Prism Coder MCP Server; it is captured when the server passes a live MCP handshake. The description above is what the project publishes.
