Overview

Description from the maker (original English)

Search the Couchbase documentation from your MCP client via a hosted documentation agent.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory
  • You need to fill in: CB_AGENT_IP_SALT

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: CB_MCP_TRANSPORT, CB_MCP_HOST, CB_MCP_PORT, CB_AGENT_BASE_URL, CB_AGENT_IP_SALT

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "couchbase-guru": {
      "command": "uvx",
      "args": [
        "couchbase-guru"
      ],
      "env": {
        "CB_MCP_TRANSPORT": "your-value",
        "CB_MCP_HOST": "your-value",
        "CB_MCP_PORT": "your-value",
        "CB_AGENT_BASE_URL": "your-value",
        "CB_AGENT_IP_SALT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add couchbase-guru --env CB_MCP_TRANSPORT=your-value --env CB_MCP_HOST=your-value --env CB_MCP_PORT=your-value --env CB_AGENT_BASE_URL=your-value --env CB_AGENT_IP_SALT=your-value -- uvx couchbase-guru

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "couchbase-guru": {
      "command": "uvx",
      "args": [
        "couchbase-guru"
      ],
      "env": {
        "CB_MCP_TRANSPORT": "your-value",
        "CB_MCP_HOST": "your-value",
        "CB_MCP_PORT": "your-value",
        "CB_AGENT_BASE_URL": "your-value",
        "CB_AGENT_IP_SALT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "couchbase-guru": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "couchbase-guru"
      ],
      "env": {
        "CB_MCP_TRANSPORT": "your-value",
        "CB_MCP_HOST": "your-value",
        "CB_MCP_PORT": "your-value",
        "CB_AGENT_BASE_URL": "your-value",
        "CB_AGENT_IP_SALT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • CB_MCP_TRANSPORT env
    Transport mode for the server (stdio or http). Default is stdio.
  • CB_MCP_HOST env
    Host to run the MCP server on (default: 127.0.0.1). Used only for HTTP transport mode.
  • CB_MCP_PORT env
    Port to run the MCP server on (default: 8000). Used only for HTTP transport mode.
  • CB_AGENT_BASE_URL env
    Base URL of the documentation agent backend. Set this to run against your own self-hosted agent; if unset, the public agent is used.
  • CB_AGENT_IP_SALT secret env
    Secret salt used to pseudonymize client IPs (HTTP transport). Set a shared value for consistent hashing across multiple instances; a local salt is generated when unset.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Couchbase Guru safe?

It passed 1 of 1 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?

You need to fill in: CB_AGENT_IP_SALT

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 –, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv), Docker on your computer.

What can I use instead?

Couchbase Guru MCP Server

An MCP server that lets LLMs search the Couchbase documentation from your MCP client. It exposes a single tool, ask_couchbase_docs, which forwards your question to a hosted retrieval-augmented (RAG) documentation agent and returns an answer with source links.

No Couchbase cluster or credentials required. The server talks only to the documentation agent backend, not to your data.

Tool

Tool NameDescription
ask_couchbase_docsAnswer a question about any Couchbase product, feature, SDK, service, tutorial, or example by searching the official documentation. Returns a natural-language answer followed by the documentation source URLs.

Ask complete, self-contained questions — the backend has no conversation history, so include the product, version, and language where relevant (e.g. _"How do I create a primary index with the Python SDK in Couchbase Server 7.6?"_).

Prerequisites

Configuration

The server can be run from the prebuilt PyPI package or from source with uv. It works with zero configuration — the public documentation agent is used by default.

Running from PyPI
{

"mcpServers": { "couchbase-guru": { "command": "uvx", "args": ["couchbase-guru"] } } }

If you already have other MCP servers configured, add this entry to the existing mcpServers object.

Running from Source

Clone the repository:

git clone https://github.com/Couchbase-Ecosystem/couchbase-guru.git

Then point your MCP client at it:

{

"mcpServers": { "couchbase-guru": { "command": "uv", "args": [ "--directory", "path/to/cloned/repo/couchbase-guru/", "run", "src/mcp_server.py" ] } } }

path/to/cloned/repo/couchbase-guru/ should be the path to the cloned repository on your machine. Don't forget the trailing slash.

Options

All options are optional and can be set via CLI argument or environment variable:

CLI ArgumentEnvironment VariableDescriptionDefault
--transportCB_MCP_TRANSPORTTransport mode: stdio or httpstdio
--hostCB_MCP_HOSTHost for HTTP transport mode127.0.0.1
--portCB_MCP_PORTPort for HTTP transport mode8000
--agent-base-urlCB_AGENT_BASE_URLBase URL of the documentation agent backend. Set this to run against your own self-hosted agent; if unset, the public agent is used.Public agent
--agent-ip-saltCB_AGENT_IP_SALTSecret salt used to pseudonymize client IPs (HTTP transport). Set a shared value for consistent hashing across multiple instances; a local salt is generated when unset.Auto-generated

Check the installed version with:

uvx couchbase-guru --version

Self-hosting the documentation agent

By default the server uses a shared, public documentation agent, so most users need no setup. If you run your own agent backend, point the server at it:

uvx couchbase-guru --agent-base-url https://your-agent.example.com

Rate limiting & privacy

The public agent applies fair-use rate limits. To support this, the server sends a pseudonymous device identifier to the backend (in the User-Agent header):

  • stdio: a random id generated once and stored in a per-user file on your machine.
  • HTTP: a salted, one-way hash of the connecting IP — the raw address is never sent.

No question content or personal data is persisted by the MCP server itself. If you prefer not to share a rate-limit signal, self-host the agent (see above).

Client-specific configuration

Claude Desktop

  1. Edit the configuration file (see the MCP quickstart guide):
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  1. Add the configuration to the mcpServers section.
  2. Restart Claude Desktop.

Logs: ~/Library/Logs/Claude (macOS) or %APPDATA%\Claude\Logs (Windows).

Cursor

  1. In Cursor, go to Cursor Settings > Tools & Integrations > MCP Tools.
  2. Add the configuration manually, or use the one-click Install in Cursor link.
  3. Save, then refresh to confirm the server is enabled.

Logs: in the bottom panel, click Output and select Cursor MCP from the dropdown.

Windsurf Editor

  1. Open Command Palette > Windsurf MCP Configuration Panel (or Settings > Advanced > Cascade > Model Context Protocol (MCP) Servers).
  2. Click Add Server > Add custom server and add the configuration.
  3. Save, then refresh to confirm the server is enabled.

See the Windsurf MCP documentation for details.

VS Code

  1. Create .vscode/mcp.json in your workspace (or run MCP: Open User Configuration for a global config).
  2. VS Code uses servers as the top-level key (not mcpServers):
   {

"servers": { "couchbase-guru": { "command": "uvx", "args": ["couchbase-guru"] } } }

  1. Once saved, use the inline action list to Start/Stop/manage the server.

See the VS Code MCP docs for details.

JetBrains IDEs

  1. Install the AI Assistant or Junie plugin.
  2. Navigate to Settings > Tools > AI Assistant or Junie > MCP Server.
  3. Click "+", add the configuration, and click Save, then Apply.

Logs: Help > Show Log in Finder (Explorer) > mcp > couchbase-guru.

Streamable HTTP transport mode

The server can run in Streamable HTTP mode so multiple clients can connect to one instance. Check that your MCP client supports this transport first.

uvx couchbase-guru --transport=http --port=8000

The server will be available at http://localhost:8000/mcp:

{

"mcpServers": { "couchbase-guru-http": { "url": "http://localhost:8000/mcp" } } }

This mode does not include authorization support.

Docker

Build the image:

docker build -t couchbase-guru .

Run it (stdio by default; no credentials needed):

{

"mcpServers": { "couchbase-guru-docker": { "command": "docker", "args": ["run", "--rm", "-i", "couchbase-guru"] } } }

For HTTP transport, publish the port and set the transport:

docker run --rm -i \

-e CB_MCP_TRANSPORT=http \ -e CB_MCP_HOST=0.0.0.0 \ -e CB_MCP_PORT=8000 \ -p 8000:8000 \ couchbase-guru

Risks associated with LLMs

  • The use of large language models and similar technology involves risks, including the potential for inaccurate or harmful outputs.
  • Couchbase does not review or evaluate the quality or accuracy of such outputs, and such outputs may not reflect Couchbase's views.
  • You are solely responsible for determining whether to use large language models and related technology, and for complying with any applicable license terms, terms of use, and your organization's policies.

Troubleshooting

  • Confirm that uv/uvx is installed and on your PATH. You may need to provide an absolute path to uv/uvx in the command field.
  • If a search times out, the documentation backend may be busy — retry in a moment.
  • To rule out the public backend, run against your own agent with --agent-base-url.
  • If running from source after updating the repo, run uv sync to refresh dependencies.
  • Check your MCP client's logs (locations above) for errors.

Testing

Unit tests run offline (the backend is mocked):

uv sync --extra dev

uv run pytest tests/

Integration tests exercise the tool end-to-end against a live agent backend and are opt-in:

CB_MCP_RUN_INTEGRATION=1 uv run pytest tests/test_docs_tools.py

By default they use the public agent; set CB_AGENT_BASE_URL to target a different backend.
