- Connects to a local code repository for analysis.
- Provides the get_codebase_context tool for AI clients.
- Uses Gemini 2.0 Flash (or custom model) with 1M input window.
- Supports SSE (recommended) and stdio transport protocols.
- Tracks token usage and allows configurable token limits (500k, 800k, 1M).
- Accepts user-attached files and additional context from queries.

From the repository

Running As A Standalone Server Recommended

By default, the server runs in SSE mode, which allows you to:

- Start the server independently
- Connect from multiple clients
- Keep it running while restarting clients

python kontxt_server.py --repo-path /path/to/your/codebase

PS: you can usepwdto list the project path

The server will start onhttp://127.0.0.1:8080/sseby default.

python kontxt_server.py --repo-path /path/to/your/codebase --host 0.0.0.0 --port 6900

The server can be stopped by pressingCtrl+Cin the terminal where it's running. The server will attempt to close gracefully with a 3-second timeout.

Alternative Running With Stdio Transport

If you prefer to have the client start and manage the server process:

python kontxt_server.py --repo-path /path/to/your/codebase --transport stdio

For this mode, configure your~/.cursor/mcp.jsonfile like this:

{ "mcpServers": { "kontxt-server": { "serverType": "stdio", "command": "python", "args": ["/absolute/path/to/kontxt_server.py", "--repo-path", "/absolute/path/to/your/codebase", "--transport", "stdio"], "env": { "GEMINI_API_KEY": "your-api-key-here" } } } }

- --repo-path PATH:Required. Absolute path to the local code repository to analyze.
- --gemini-api-key KEY: Google Gemini API Key (overrides.envif provided).
- --token-threshold NUM: Target maximum token count for the context. Allowed values are:

- 500000
- 800000 (default)
- 1000000

For security, wildcard CORS is not used. By default, only loopback origins are allowed:

- http://127.0.0.1,http://localhost, and the boundhost:port.

To allow specific web clients during development, pass explicit origins or use an env var:

python kontxt_server.py \ --repo-path /path/to/your/codebase \ --cors-origins http://localhost:3000,http://127.0.0.1:5173 # or via environment variable KONTXT_CORS_ORIGINS="http://localhost:3000,http://127.0.0.1:5173" \ python kontxt_server.py --repo-path /path/to/your/codebase

- Allowed methods:GET,OPTIONS. Headers: all. Credentials: off unless--cors-credentialsis set.

Kontxt MCP Server

A Model Context Protocol (MCP) server that tries to solve condebase indexing (until agents can).

Features

- Connects to a user-specified local code repository.
- Provides the (get_codebase_context) tool for AI clients (like Cursor, Claude Desktop).
- Uses Gemini 2.0 Flash's 1M input window internally to analyze the codebase and generate context based on the user's client querry.
- Flash itself can use internal tools (list_repository_structure, read_files, grep_codebase) to understand the code.
- Supports both SSE (recommended) and stdio transport protocols.
- Supports user-attached files/docs/context from client's queries for more targeted analysis.
- Tracks token usage and provides detailed analysis of API consumption.
- User-configurable token limit for context generation (options: 500k, 800k, or 1M tokens; default: 800k).

Setup

1. Clone/Download: Get the server code.
2. Create Environment:

    python -m venv venv

    source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install Dependencies:

    pip install -r requirements.txt

4. Install tree: Ensure the tree command is available on your system.
- macOS: brew install tree
- Debian/Ubuntu: sudo apt update && sudo apt install tree
- Windows: Requires installing a port or using WSL.
5. Configure API Key:
- Copy .env.example to .env.
- Edit .env and add your Google Gemini API Key:

      GEMINI_API_KEY="YOUR_ACTUAL_API_KEY"

- Alternatively, you can provide the key via the --gemini-api-key command-line argument.

Running as a Standalone Server (Recommended)

By default, the server runs in SSE mode, which allows you to:
- Start the server independently
- Connect from multiple clients
- Keep it running while restarting clients

Run the server:

python kontxt_server.py --repo-path /path/to/your/codebase

PS: you can use ``pwd` to list the project path

The server will start on http://127.0.0.1:8080/sse by default.


For additional options:

python kontxt_server.py --repo-path /path/to/your/codebase --host 0.0.0.0 --port 6900


Shutting Down the Server

The server can be stopped by pressing Ctrl+C in the terminal where it's running. The server will attempt to close gracefully with a 3-second timeout.


Connecting to the Server from client (Cursor example)

Once your server is running, you can connect Cursor to it by editing your ~/.cursor/mcp.json file:


{
  "mcpServers": {
    "kontxt-server": {
      "serverType": "sse",
      "url": "http://localhost:8080/sse"
    }
  }
}

PS: remember to always refresh the MCP server on Cursor Settings or other client to connect to the MCP via sse
Alternative: Running with stdio Transport
If you prefer to have the client start and manage the server process:
python kontxt_server.py --repo-path /path/to/your/codebase --transport stdio

For this mode, configure your ~/.cursor/mcp.json file like this:


{
  "mcpServers": {
    "kontxt-server": {
      "serverType": "stdio",
      "command": "python",
      "args": ["/absolute/path/to/kontxt_server.py", "--repo-path", "/absolute/path/to/your/codebase", "--transport", "stdio"],
      "env": {
        "GEMINI_API_KEY": "your-api-key-here"
      }
    }
  }
}

Command Line Arguments

- --repo-path PATH: Required. Absolute path to the local code repository to analyze. ---gemini-api-key KEY: Google Gemini API Key (overrides .envif provided). ---token-threshold NUM: Target maximum token count for the context. Allowed values are: - 500000 - 800000 (default) - 1000000 ---gemini-model NAME: Specific Gemini model to use (default: models/gemini-2.5-flash-preview-04-17). ---tokenizer-model NAME: Hugging Face tokenizer id for token estimation (default: google/gemma-7b; override via KONTXT_TOKENIZER_MODEL). ---transport {stdio,sse}: Transport protocol to use (default: sse). ---host HOST: Host address for the SSE server (default: 127.0.0.1). ---port PORT: Port for the SSE server (default: 8080). ---cors-origins ORIGINS: Comma-separated list of allowed CORS origins. If omitted, defaults to loopback only. ---cors-credentials: Allow credentials for CORS (disabled by default).


CORS Configuration
For security, wildcard CORS is not used. By default, only loopback origins are allowed:

- http://127.0.0.1, http://localhost, and the bound host:port.


To allow specific web clients during development, pass explicit origins or use an env var:

``bash
python kontxt_server.py \
--repo-path /path/to/your/codebase \
--cors-origins http://localhost:3000,http://127.0.0.1:5173
