Works with Claude, with some setup first

Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Context Bridge for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "context-bridge": { "command": "npx", "args": [ "-y", "@contextbridge_ai/mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Context Bridge tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

Common questions

Is Context Bridge safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 6 months ago, and the latest version (0.1.3) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

ContextBridge

ContextBridge is a context portability tool for AI conversations. This package publishes the MCP server surface: it compresses an in-progress conversation into a structured context block that preserves the user's goal, confirmed decisions, current state, open threads, artifacts, constraints, recent pivots, and suggested next step, then formats that handoff so another AI can continue without forcing the user to restate everything.

The published npm artifact is the stdio MCP server for Claude Desktop, agent runtimes, and other MCP-compatible hosts. The browser extension runtime is developed in the same repository, but it is not part of this MCP Registry publishing flow.

Published Links

Install In Claude Desktop

Add this to your Claude Desktop MCP config (~/Library/Application Support/Claude/claude_desktop_config.json):

{

"mcpServers": { "contextbridge": { "command": "npx", "args": ["-y", "@contextbridge_ai/mcp"], "env": { "GROQ_API_KEY": "your_groq_api_key_here" } } } }

Or with OpenAI:

{

"mcpServers": { "contextbridge": { "command": "npx", "args": ["-y", "@contextbridge_ai/mcp"], "env": { "OPENAI_API_KEY": "your_openai_api_key_here", "OPENAI_MODEL": "gpt-4.1-mini" } } } }

For a hosted no-key lane instead of BYOK:

{

"mcpServers": { "contextbridge": { "command": "npx", "args": ["-y", "@contextbridge_ai/mcp"], "env": { "CONTEXTBRIDGE_HOSTED_URL": "https://your-hosted-endpoint.example/v1", "CONTEXTBRIDGE_HOSTED_MODEL": "mistralai/Mistral-7B-Instruct-v0.2" } } } }

Available MCP Tools

compress_context

Parameters:

  • transcript (string, required): the raw conversation transcript to compress.
  • provider ("openai" | "openai-chat" | "google" | "groq" | "custom" | "hosted", optional): provider override.
  • model (string, optional): model override for the selected lane.
  • apiKey (string, optional): BYOK API key override.
  • baseUrl (string, optional): API base URL override.
  • hostedApiKey (string, optional): optional auth key for the hosted lane.
format_for_target

Formats a compressed context block for a destination platform.

Parameters:

  • context_block (object, required): a validated ContextBridge compressed context block.
  • target ("claude" | "chatgpt" | "gemini", required): destination AI platform.
resume_context

Builds a destination-ready landing package from a compressed context block.

Parameters:

  • context_block (object, required): a validated ContextBridge compressed context block.
  • target ("claude" | "chatgpt" | "gemini", required): destination AI platform.

BYOK Setup

ContextBridge auto-selects the OpenAI Responses lane when a BYOK key is present.

Environment variables:

OPENAI_API_KEY=your_openai_api_key_here

OPENAI_MODEL=gpt-4.1-mini OPENAI_BASE_URL=https://api.openai.com/v1

Additional supported provider overrides:

GOOGLE_API_KEY=your_google_api_key_here

GOOGLE_MODEL=gemini-2.5-pro GOOGLE_BASE_URL=https://generativelanguage.googleapis.com/v1beta/openai

GROQ_API_KEY=your_groq_api_key_here GROQ_MODEL=llama-3.3-70b-versatile GROQ_BASE_URL=https://api.groq.com/openai/v1

CONTEXTBRIDGE_API_KEY=your_custom_api_key_here CONTEXTBRIDGE_MODEL=your_custom_model_here CONTEXTBRIDGE_BASE_URL=https://your-endpoint.example/v1 CONTEXTBRIDGE_PROVIDER=custom

Hosted Lane Setup

The hosted lane is the no-key path for end users who do not bring their own provider credentials.

Environment variables:

CONTEXTBRIDGE_HOSTED_URL=https://your-hosted-endpoint.example/v1

CONTEXTBRIDGE_HOSTED_MODEL=mistralai/Mistral-7B-Instruct-v0.2 CONTEXTBRIDGE_HOSTED_API_KEY=

Selection priority:

  1. Explicit apiKey option passed into compression uses the OpenAI Responses BYOK lane.
  2. OPENAI_API_KEY uses the OpenAI Responses BYOK lane.
  3. CONTEXTBRIDGE_HOSTED_URL uses the hosted lane.

Contributions are welcome. The highest-leverage areas are extraction quality evaluation, browser collector resilience, destination formatting quality, hosted-lane infrastructure, and real-world handoff testing across platforms.
