What is the Convex MCP Server?

Connect your Convex deployment to any AI agent and manage your application's data and logic through natural conversation. This server allows you to interact with your real-time database and serverless functions without leaving your AI interface.

What you can do

Data Fetching — Execute read-only queries to retrieve documents and state from your Convex tables.
Transactional Updates — Run mutations to modify data with full ACID guarantees directly from the agent.
Side Effects & APIs — Trigger Convex actions for external API calls, heavy computation, or non-transactional logic.
Flexible Execution — Call functions using standard colon notation or URL-style identifiers for maximum compatibility.

How it works

Subscribe to this server
Enter your Convex Deployment URL (and optional Access Key)
Start querying and mutating your data from Claude, Cursor, or any MCP-compatible client

Who is this for?

Full-stack Developers — Debug data, run migrations, or check state directly from your IDE or chat.
Product Managers — Query live application metrics and user data using natural language without writing code.
Support Teams — Inspect and update user records or trigger administrative actions through a secure AI interface.

Built-in capabilities (4)

run_action

Call a Convex action function

run_function

g., "messages/list" instead of "messages:list"). Call a Convex function by its URL identifier

run_mutation

Call a Convex mutation function

run_query

Use this for fetching data. Call a Convex query function

Why LlamaIndex?

LlamaIndex agents combine Convex tool responses with indexed documents for comprehensive, grounded answers. Connect 4 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

FAQ

Frequently asked questions

What is the difference between run_query and run_mutation?

Use run_query for read-only operations that fetch data. Use run_mutation when you need to write, update, or delete data transactionally in your database.

Can I call external APIs using this server?

Yes, by using the run_action tool. Actions in Convex are designed for side effects like calling third-party APIs or performing long-running tasks.

How do I reference functions in subdirectories?

You can use run_query with colon notation (e.g., 'folder/file:function') or use run_function which accepts URL-style identifiers with slashes.

How does LlamaIndex connect to MCP servers?

Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.

Can I combine MCP tools with vector stores?

Yes. LlamaIndex agents can query Convex tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
