## Description
Bubbles: save chat context once, use it in ChatGPT, Claude, Gemini, Grok, Perplexity and Cursor.

## Claude Desktop Quick Installation
No generated config for this server: it installs through its own setup steps.

The project's own setup steps (from https://sixteenbridges.com/docs/mcp), copied verbatim. Run them in order; they are not an mcpServers config.

1. Add to Claude Code:

```sh
claude mcp add --transport http sixteen-bridges https://mcp.sixteenbridges.com/mcp
```

2. Add to Codex:

```sh
codex mcp add sixteen-bridges --url https://mcp.sixteenbridges.com/mcp
```

3. Sign in:

```sh
codex mcp login sixteen-bridges
```

4. Add to Gemini CLI:

```sh
gemini mcp add --transport http sixteen-bridges https://mcp.sixteenbridges.com/mcp
```

5. Sign in:

## Documentation

## What Sixteen Bridges does

Sixteen Bridges centers on portable chat context. It lets users save context from a conversation once and reuse that context across several AI applications: ChatGPT, Claude, Gemini, Grok, Perplexity, and Cursor.

The primary use case is continuity between separate conversations or products. Rather than restating background information each time an interaction moves to another supported application, an agent can work with context that has already been saved. This makes the server relevant for workflows where people switch between AI tools or maintain related conversations in more than one place.

## How it works

The workflow has two basic stages: save chat context, then use it again. An MCP-compatible agent interacts with Sixteen Bridges to preserve the relevant conversation information. Supported applications can then draw on that saved context when continuing work.

This model separates context from an individual chat session. The same saved information can support interactions in the named applications, including ChatGPT, Claude, Gemini, Grok, Perplexity, and Cursor. The service is therefore intended for sharing conversational context across products rather than limiting it to one assistant.

## Tools and capabilities

Sixteen Bridges provides capabilities for:

- Saving chat context for later reuse
- Reusing saved context across supported AI applications
- Carrying information between ChatGPT, Claude, Gemini, Grok, Perplexity, and Cursor
- Supporting workflows that move between multiple AI products

The central distinction is persistence and reuse: context is saved once, then made available where it is needed across the supported application set.

## Limitations and notes

Sixteen Bridges is focused on chat-context sharing. Its stated application coverage includes ChatGPT, Claude, Gemini, Grok, Perplexity, and Cursor. Choose it when the main requirement is carrying conversational context between these products, rather than when the primary need is an unrelated data source, productivity API, or general-purpose automation tool.

The service is most useful when the same background, instructions, or conversation details need to follow work across different AI interfaces. Its value depends on using applications within the supported set and on having context worth preserving between interactions.
