How to Use the Transifex MCP in LlamaIndex

Q: How do I index Transifex languages with LlamaIndex?

First, call listlanguages and feed the resulting list into your indexing process. This makes every supported language code a searchable piece of knowledge, allowing users to query based on locale rather than just knowing the ID.

Q: Can I use LlamaIndex to answer questions about Transifex project slugs?

Yes. You can run listprojects and index the output containing all available project slugs. Your agent then queries this index, giving answers grounded in your historical project data.

Q: Do I need a specific project slug when indexing Transifex content with LlamaIndex?

While getproject requires a slug, you can index broader lists. If you call listresources, the resulting list of resources is enough to build a searchable knowledge base without needing individual slugs for every single item.

Indexing Project Structures

LlamaIndex lets you index project details by calling `get_project` (o:org-slug:p:project-slug). The output—the full context of that specific project—becomes part of your searchable knowledge base. You won't hallucinate; your queries are grounded in actual Transifex data. Furthermore, you can use `list_projects` to index an entire list of available projects across your account. This lets a user ask broad questions like 'What work areas do we have?' and get accurate answers from the indexed results.

Retrieving Resource Details

You can build RAG applications that answer specific resource questions using `get_resource` (o:org-slug:p:project-slug:r:resource-slug). The full details of that single resource are indexed, making it instantly available for semantic search. Want to check a string's source? Use `get_resource_string`. Indexing these specific strings lets you query historical or current translations and find the exact context without running another live API call.

Discovering Content Scope

The server offers several list functions to build a comprehensive index. Running `list_organizations` indexes every group you belong to, while `list_languages` records all supported language codes. For content itself, calling `list_resources` or `list_resource_strings` and indexing the results allows your agent to answer questions like 'Which projects have resources?' based on stored data.

Setup guide

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

Common questions about Transifex MCP in LlamaIndex

First, call `list_languages` and feed the resulting list into your indexing process. This makes every supported language code a searchable piece of knowledge, allowing users to query based on locale rather than just knowing the ID.

Yes. You can run `list_projects` and index the output containing all available project slugs. Your agent then queries this index, giving answers grounded in your historical project data.

This server handles various identifiers like resource slugs, organization slugs, and language codes. All these types are indexed into the vector store, allowing your agent to treat them all as searchable facts.

While `get_project` requires a slug, you can index broader lists. If you call `list_resources`, the resulting list of resources is enough to build a searchable knowledge base without needing individual slugs for every single item.

The server touches language codes, organization identifiers, and resource strings. These are the specific types of data that get indexed into your knowledge base, making them retrievable for semantic search.
