How to Use the Handlebars Template Compiler MCP in Google ADK

Q: How do I add the Handlebars Template Compiler to Google ADK?

Use the McpToolset class with your server URL. Pass this object into your LlmAgent configuration to make compiletemplate available for your agent to call.

Q: Can I filter the Handlebars Template Compiler tools in Google ADK?

Yes. Use the toolnames filter in your McpToolset configuration. This restricts the agent to only using compiletemplate if that is all you need.

Perplexity

Reliable rendering for Google ADK agents

Stop letting your agents guess how to bind variables to HTML. The `compile_template` tool provides a standard way to process your templates, ensuring consistent output for your enterprise workflows. It works by processing your input against a strict engine. You get valid HTML every time, even when your agent is working with massive datasets from BigQuery.

Support for advanced logic in Google ADK

Inject `{{#each}}` loops and conditional logic into your templates without the risk of hallucinated syntax. The compiler handles these structures correctly, which is vital for personalized marketing campaigns. Your agent can now offload the heavy lifting to `compile_template`. This keeps your agent's reasoning focused on strategy while the server handles the template syntax.

Integration with Google Cloud pipelines

Configure your `McpToolset` to include this server and give your Gemini-powered agents a reliable rendering engine. It fits right into your existing infrastructure without adding unnecessary latency. This setup prevents the common errors found in automated email generation. You gain a predictable step in your pipeline that guarantees your final templates are ready for distribution.

Setup guide

Set up Handlebars Template Compiler 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 Handlebars Template Compiler 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="Handlebars Template Compiler_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Handlebars Template Compiler tools via MCP.",
    tools=mcp_tools,
)

Common questions about Handlebars Template Compiler MCP in Google ADK

Use the `McpToolset` class with your server URL. Pass this object into your `LlmAgent` configuration to make `compile_template` available for your agent to call.

It supports both Stdio and HTTP. For Google ADK, we recommend HTTP for easier scaling across your cloud-based agent infrastructure.

Yes. Use the `tool_names` filter in your `McpToolset` configuration. This restricts the agent to only using `compile_template` if that is all you need.

By moving away from LLM-based string manipulation, you eliminate syntax errors. The compiler ensures that your Handlebars tags are always closed and correctly bound.

Security is handled via isolated execution. Your templates and data are ephemeral, meaning they only exist in memory during the compilation process and are wiped immediately after.
