How to Use the Tyk MCP in Google ADK

Q: How does the Google ADK interact with Tyk for API key management?

The agent uses createkey, getkey, and updatekey to manage credentials. This means your enterprise workflows can programmatically generate, retrieve, or refresh keys without manual intervention.

Q: Can the Google ADK list all available API definitions?

Yes, it calls listapis. This lets the agent know exactly what APIs are available in Tyk, providing a necessary inventory check before attempting any action or data retrieval.

Q: If I change security rules with Google ADK, how do I make sure they take effect?

You use updatepolicy to modify the rule and then must execute hotreload. This forces Tyk Gateway to apply the new policy immediately across all services.

Q: Does the Google ADK handle deleting credentials? What data types are involved?

It handles deletion using deletekey or deletepolicy. The agent works with API keys, which are essentially strings representing unique session objects and tokens.

Q: What happens if I use the Google ADK to update a policy?

The agent executes updatepolicy. This function modifies an existing rule within Tyk's security framework, maintaining consistency across your large-scale applications.

Define and List APIs

The agent can list all available API definitions using `list_apis`, giving it a full catalog of what the Tyk Gateway supports. Need to add a new endpoint? It uses `create_api_definition` to write that definition into your system. This process ensures your Gemini-powered agents only try to interact with APIs that are properly configured and accessible.

Maintain Security Policies

Your agent controls the security layer using tools like `create_policy` and `delete_policy`. It can also check existing rules by calling `get_policy`. This gives your enterprise system precise, programmatic control over access. If you change a policy, remember to run `update_policy`, followed by `hot_reload` so the new rule immediately affects all connected services.

Manage User Credentials

The agent handles user identity using API keys. It can create an entire organization's set of keys via `create_org_key`, or generate a single key with `create_key`. This is vital for managing access across large, multi-tenant Google Cloud deployments. Need to restrict someone? The agent uses `delete_key` to revoke immediate access or `update_key` if credentials need refreshing.

Setup guide

Set up Tyk MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Tyk tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Tyk_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Tyk tools via MCP.",
    tools=mcp_tools,
)
