Built-in capabilities (4)
Tools for your AI Agents to operate Convex
Ask your AI agent "Run the Convex query 'messages:list' with no arguments." and get the answer without opening a single dashboard. With 4 tools connected to real Convex data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by Vinkius — your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you the infrastructure to connect your AI agents to thousands of MCP servers — and deploy your own to the Vinkius Edge. Your credentials stay yours. Your data flows directly between your agent and the API. DLP blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade routing and governance, zero maintenance.

Run action on Convex
Call a Convex action function
Run function on Convex
g., "messages/list" instead of "messages:list"). Call a Convex function by its URL identifier
Run mutation on Convex
Call a Convex mutation function
Run query on Convex
Use this for fetching data. Call a Convex query function
What the Convex MCP Server unlocks
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
1. Subscribe to this server
2. Enter your Convex Deployment URL (and optional Access Key)
3. 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.
Frequently asked questions about the Convex MCP Server
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.
