How to Use the Tyk MCP in LlamaIndex

Q: How does Tyk MCP Server help LlamaIndex index data?

LlamaIndex consumes the output of Tyk's tools—like getpolicy or createkey. It takes that structured API data and embeds it into a vector store, making it semantically searchable.

Q: Can I use Tyk MCP Server to verify policies with LlamaIndex?

Yes. You can feed the output of getpolicy into your index, then query it naturally: 'Does policy A allow access from source B?' The answer is grounded in the indexed rule set.

Q: Is Tyk MCP Server suitable for complex credential tracking with LlamaIndex?

It's perfect. By indexing outputs like createkey and deletekey, you build a historical record of credentials, allowing users to 'ask' about old key statuses.

Ground your knowledge with LlamaIndex and Tyk MCP Server's API data index.

Indexing API Definitions

LlamaIndex can ingest the results of `list_apis` to build a searchable record of all endpoints. Instead of just printing a list, you create an indexed knowledge base around them. This lets your RAG application answer questions like 'What are our available APIs?' using data grounded in the actual gateway configuration.

Querying API Keys and Policies

The tool `get_policy` outputs structured data that LlamaIndex can index. You can then query your knowledge store to ask, 'What is the policy for key XYZ?' without needing an exact function call. This transforms credentials from simple variables into retrievable, context-aware facts.

Managing Credentials via Indexing

When you run `create_org_key` or `delete_policy`, the resulting data and metadata become part of your indexed knowledge. This allows future queries to reference past state changes. The system doesn't just execute; it records that an action happened, which is vital for auditing complex API deployments.

Setup guide

Set up Tyk MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Tyk MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Tyk tools.",
)
response = await agent.run("List recent Tyk data")
