Model Context Protocol MCP is a protocol that standardizes providing context to LLMs like Claude, ChatGPT and MistralAI.
CrateDB MCP server lets these LLMs operate directly on CrateDB enabling use cases like:
- Answer questions about your data and database state
- Help you debug and optimize queries directly on the database
To use a MCP server you need a client that supports the protocol, the most notable ones are: Claude Desktop, ChatGTP desktop, OPenAI agents SDK and Cursor.
For questions like optimizing queries and CrateDB specific syntax/capabilities, we encourage the
LLMs to fetch https://cratedb.com/docs to offer the most accurate possible information.
These are examples of questions that have been tested and validated by the team. Remember that LLMs can still hallucinate and give incorrect answers.
- Optimize this query: "SELECT * FROM movies WHERE release_date > '2012-12-1' AND revenue"
- Tell me about the health of the cluster
- What is the storage consumption of my tables, give it in a graph.
- How can I format a timestamp column to '2019 Jan 21'.
We do not recommend letting the LLMs insert data or modify columns by itself, as such we tell the
LLMs to only allow 'SELECT' statements in the cratedb_sql tool, you can jailbreak this against
our recommendation.
