How to Use the Tumblr MCP in LlamaIndex

Q: How do I search Tumblr using LlamaIndex?

First, you use listtaggedposts to gather the raw content. Then, that output is indexed into a vector store. You query the index later for semantic answers grounded in the specific posts.

Q: Can LlamaIndex keep track of Tumblr blog data?

Yes. By indexing results from getbloginfo, you create persistent records of account details. Your knowledge base retains this metadata, allowing for complex cross-referencing over time.

Q: What if I want to compare Tumblr posts using LlamaIndex?

You run listblogposts and index the results. Later, you can ask a comparative question—like 'compare post X and post Y'—and LlamaIndex will pull all relevant data points from its stored knowledge.

Build a search index from post data

When you run `list_blog_posts`, the output isn't just passed through—it becomes part of your indexed knowledge base. You can later query that stored data to find specific posts without re-running the API call. This means if you ran a search on Tumblr today, and next week ask a question about it, LlamaIndex grounds the answer in those live results, avoiding hallucination.

Query historical blog information

Need to know what was posted years ago? You index the output from `get_blog_info` and `list_blog_posts`. When you query the knowledge base, LlamaIndex finds semantic matches across all that stored Tumblr data. It combines live API results with documents you already own into one unified, searchable source.

Search by tag history

After running `list_tagged_posts`, the resulting set of posts gets indexed. Later, if a user asks a general question about that topic—say, 'what was discussed last month'—LlamaIndex can retrieve the context from the stored API results. This is ideal for building RAG applications where past Tumblr interactions are treated as factual knowledge.

Setup guide

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

It handles them by turning API calls into searchable context. You index the output of `get_post` multiple times; then, you query across all those indexed posts at once.

The server provides blog identifiers and profile information via `get_blog_info`. LlamaIndex indexes this data structure, making every piece of metadata searchable by meaning, not just keyword.
