How to Use the Beeceptor MCP in LlamaIndex

Q: How do I load Beeceptor tools into LlamaIndex?

Grab the llama-index-tools-mcp package. Create a BasicMCPClient pointing to the endpoint, wrap it in McpToolSpec, and await totoollistasync().

Q: Can LlamaIndex filter which Beeceptor tools are available?

Yes. Pass an allowedtools array to restrict access. Limiting permissions prevents your agent from accidentally modifying rules during a read-only query.

Q: How does the agent handle multipart file downloads?

The downloadmultipart tool fetches the binary data directly. Your RAG pipeline can then route that file through a document parser for further indexing.

Index mocked API responses into LlamaIndex to query your Beeceptor MCP Server traffic semantically.

Perplexity

Vectorizing MCP Server traffic

Intercepted API payloads become fully searchable when you pipe them into your vector store. LlamaIndex pulls recent traffic using `list_requests` and chunks the JSON bodies. These chunks go straight into your database. Developers can then ask plain English questions about what happened during a test run. The agent retrieves the exact request via `get_request` and compares it against the expected schema.

Queryable mock configurations

Live proxy rules act as the source of truth for your development team. Pointing your indexer at the setup by calling `list_rules` maps the environment. Every active proxy rule becomes a searchable document. Someone asking about a specific checkout mock gets an immediate, grounded answer. The system knows exactly how the route is configured because it read the live state.

RAG over API specifications

OpenAPI specifications loaded directly into the context window expose documentation discrepancies immediately. Your setup can ingest these files using `get_spec_details` and store them alongside actual traffic logs. When a test fails, the agent cross-references the spec with the mocked response. It suggests calling `update_rule_partial` to fix a mismatched field type.

Setup guide

Set up Beeceptor 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 Beeceptor 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 Beeceptor tools.",
)
response = await agent.run("List recent Beeceptor data")

Common questions about Beeceptor MCP in LlamaIndex

Grab the `llama-index-tools-mcp` package. Create a `BasicMCPClient` pointing to the endpoint, wrap it in `McpToolSpec`, and await `to_tool_list_async()`.

Yes. Pass an `allowed_tools` array to restrict access. Limiting permissions prevents your agent from accidentally modifying rules during a read-only query.

Searching across hundreds of complex routing configurations is slow. Vector search lets you find specific error scenarios or payload structures instantly without writing custom grep scripts.

The `download_multipart` tool fetches the binary data directly. Your RAG pipeline can then route that file through a document parser for further indexing.

Vinkius runs your connection inside a zero-trust environment. Any OpenAPI definitions accessed via `upload_spec` exist only in volatile memory during the active session. We never write your endpoints to persistent disks.
