to Pydantic AI
Create your Vinkius account to connect Vald to Pydantic AI and start using all 6 AI tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code. No hosting, no server setup — just connect and start using.
Compatible with every major AI agent and IDE
What is the Vald MCP Server?
Connect your Vald cluster to any AI agent and bring distributed, high-speed approximate nearest neighbor (ANN) vector search directly to your conversational workflow.
What you can do
- Vector Search — Perform rapid semantic searches across millions of embedded data points just by querying the agent.
- Data Ingestion — Insert new high-dimensional vectors directly into the Vald index for instant future retrievability in your RAG pipelines.
- Index Management — Update the vector representations of existing records or permanently remove specific items from the engine cluster.
- Cluster Health — Automatically retrieve operational system information, agent health statuses, and node details regarding your active Vald deployment.
How it works
- Subscribe to this server
- Enter your Vald Gateway Host address
- Start performing semantic queries and updates from Claude, Cursor, or any MCP-compatible client
Your AI agent becomes the direct line to your massive vector knowledge base.
Who is this for?
- Machine Learning Engineers — rapidly test and visualize embedding changes against a live Vald instance without scripting.
- Data Scientists — execute on-the-fly 'top-k' semantic queries directly from an IDE to validate search recall results.
- DevOps Engineers — check the active engine health status and cluster info via natural language whenever anomalies happen.
- Backend Developers — quickly purge corrupted vectors or update legacy records bypassing native database terminals.

Frequently asked questions
Can my AI agent do a semantic search across my vector database?
Yes! Provided you supply the embedded query vector, your agent can issue a vector search command to the Vald Engine. It will rapidly scan millions of indexes natively using its ANN algorithms and return the top-K closest neighbors associated with your data.
How do I ensure my Vald cluster is healthy right from my CLI?
Skip complex diagnostics loops. Instruct your agent to get Vald internal engine info. It will interface directly via gRPC/REST and pull down cluster metrics including operational status, agent versions, and basic diagnostic health. This is vital for MLOps managing production RAG pipelines needing constant reassurance.
Can I permanently purge a corrupted vector embedding?
When a document becomes stale in your knowledge base, you must remove its embedding. Ask the AI agent: permanently delete vector ID 'doc-xyz'. Using the removeVector capability, it targets your cluster and ensures the outdated semantic representation is fully expunged without risking other node data.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Vald MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
