Jentic MCP Plugin

Why Use Jentic MCP?

Jentic MCP empowers developers to discover and integrate external APIs and workflows rapidly—without the need to write or maintain any API-specific code. By leveraging the MCP protocol and Jentic’s agentic runtime, developers can:

• Search for APIs and workflows by capability, not by vendor or implementation.
• Instantly generate integration code samples that are agnostic to specific API details.
• Avoid boilerplate and reduce maintenance by relying on standardized, declarative integration.
• Focus on building features, while Jentic MCP handles the complexity of API interaction.

API Tools

The Jentic MCP Plugin provides the following tools:

1. search_apis: Search for APIs in the Jentic directory that match specific functionality needs
2. load_execution_info: Retrieve detailed specifications for APIs and operations from the Jentic directory. This will include auth information you may need to provide in your mcpServers.jentic.env configuration.
3. execute: Execute a specific API or workflow operation.

Getting Started

The recommended method is to run the server directly from the GitHub repository using uvx. You will need to install uv first using:

brew install uv or pip install uv

Agent API Key

Create an agent at https://app.jentic.com/sign-in and copy its API key.

export JENTIC_AGENT_API_KEY=<your-agent-api-key>

Set the key in your MCP client configuration as shown below.

The location of the configuration file depends on the client you are using and your OS. Some common examples:

• Windsurf: ~/.codeium/windsurf/mcp_config.json
• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
• Claude Code: ~/.claude.json
• Cursor: ~/cursor/.mcp.json

For other clients, check your client's documentation for how to add MCP servers.

{
    "mcpServers": {
        "jentic": {
            "command": "uvx",
            "args": [
                "--from",
                "git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp",
                "mcp"
            ],
            "env": {
                "JENTIC_AGENT_API_KEY": "<your-agent-api-key>"
            }
        }
    }
}

Note: After saving the configuration file, you may need to restart the client application (Windsurf, Claude Desktop) for the changes to take effect.

MCP Tool Use

Once the MCP server is running, you can easily use the MCP tools in your LLM agent to discover and execute APIs and workflows.

1. search_apis: Search for APIs in the Jentic directory that match specific functionality needs
2. load_execution_info: Retrieve detailed specifications for APIs and operations from the Jentic directory. This will include auth information you may need to provide in your mcpServers.jentic.env configuration.
3. execute: Execute a specific API or workflow operation.

Environment Variables

When you are using an API that requires authentication, the load_execution_info tool will describe the required environment variables. You environment variables via the command line in Windsurf, although in some clients like Claude Desktop, you'll need to add them to your MCP config:

{
    "mcpServers": {
        "jentic": {
            "command": "uvx",
            "args": [
                "--from",
                "git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp",
                "mcp"
            ],
            "env": {
                "DISCORD_BOTTOKEN=": "YOUR BOT TOKEN"
            }
        }
    }
}

Alternative (Using Local Path for Development):

Use this if you are actively developing the MCP plugin locally. Replace /path/to/your/project/mcp with the absolute path to your project directory.

{
    "mcpServers": {
        "jentic": { 
            "command": "uvx",
            "args": [
                "--from",
                "/path/to/your/project/mcp",
                "mcp" 
            ]
        }
    }
}

Optional: Add a JENTIC_API_URL environment variable to your mcp_config.json file to point to a specific Jentic API (works with both methods):

{
    "mcpServers": {
        "jentic": {
            "command": "uvx",
            "args": [
                "--from",
                "git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp",
                "mcp"
            ],
            "env": {
                "JENTIC_API_URL": "https://your-jentic-api.url/"
            }
        }
    }
}

Once configured, restart Windsurf, and the Jentic MCP tools will be available.

You can tail the logs generated by the locally running MCP server by running:

tail /path/to/mcp/jentic_ark2_mcp.log

Installation

Installing via Smithery

To install Jentic Plugin for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @jentic/jentic-sdks --client claude

Manual Installation

Ensure you have pdm installed (pipx install pdm).

To install the package and its dependencies for development:

# From the project root directory (e.g., /Users/kc/c/sdk/mcp)
pdm install -G dev

Running the MCP Server

The Jentic MCP plugin is designed to be run using uvx, which handles environment setup and execution.

Default Mode (Stdio)

Run the MCP plugin directly using uvx, specifying the project directory as the source using --from and the mcp script:

From Local Path (Development):

# Use --from with the project directory and specify the 'mcp' script
uvx --from /path/to/your/project/mcp mcp

# Or, if running from within the project directory:
uvx --from . mcp

From Remote Repository (Recommended for general use):

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  mcp

This automatically uses the default serve --transport stdio command defined in the mcp script's callback.

HTTP Modes

The MCP server supports two HTTP transport modes:

• Standard HTTP: Traditional request-response HTTP mode
• Streamable HTTP: HTTP mode with streaming support, compatible with MCP Inspector

Standard HTTP Mode

To run the server in standard HTTP mode (e.g., for testing with claude-cli):

From Local Path (Development):

# Default HTTP (port 8010)
uvx --from /path/to/your/project/mcp mcp serve --transport http

# With custom port
uvx --from /path/to/your/project/mcp mcp serve --transport http --port 8080

# With custom host
uvx --from /path/to/your/project/mcp mcp serve --transport http --host 0.0.0.0 --port 8080

From Remote Repository (Recommended):

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  mcp serve --transport http --port 8080

Streamable HTTP Mode

To run the server in streamable HTTP mode (compatible with MCP Inspector):

From Local Path (Development):

# Default streamable HTTP (port 8010)
uvx --from /path/to/your/project/mcp mcp serve --transport streamable-http

# With custom port
uvx --from /path/to/your/project/mcp mcp serve --transport streamable-http --port 8080

# With custom host
uvx --from /path/to/your/project/mcp mcp serve --transport streamable-http --host 0.0.0.0 --port 8080

From Remote Repository (Recommended):

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  mcp serve --transport streamable-http --port 8080

Running from a Remote Git Repository

You can also run the MCP server directly from a Git repository URL without cloning it locally using uvx --from:

# Example from a specific branch and subdirectory
uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp

# Explanation:
# - git+https://... .git : The repository URL
# - @main   : The branch, tag, or commit hash
# - #subdirectory=mcp     : The folder within the repo containing the pyproject.toml

This command fetches the specified version, installs its dependencies in a temporary environment, and runs the default command (which is serve --transport stdio).

You can add other arguments like --log-level DEBUG or --mock after the URL fragment:

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  --log-level DEBUG --mock

To run in HTTP mode from a remote source:

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  serve --transport http --port 8080

To run in streamable HTTP mode from a remote source:

uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  serve --transport streamable-http --port 8080

# Run the server in HTTP mode first
uvx --from \
  git+https://github.com/jentic/jentic-sdks.git@main#subdirectory=mcp \
  mcp serve --transport http --port 8000

# Then connect claude-cli
claude-cli --mcp http://localhost:8000

Run from Local Path (Development):

# Run the server in HTTP mode first
uvx --from /path/to/your/project/mcp mcp serve --transport http --port 8000

# Then connect claude-cli
