What AI agents can do with 7 Vector Database Tools for Semantic Embedding Search
Use these tools to list indexes, query vectors, check index stats, and manage collections across your Pinecone environment.
Delete vectors
Removes specific vectors from an index based on criteria or IDs.
Describe index
Retrieves the structural configuration and parameters of a chosen Pinecone index.
Fetch vectors
Gets specific vectors using their unique IDs for immediate reference.
Get index stats
Outputs current usage statistics, including vector count and pod capacity limits.
List collections
Shows a list of all existing index collections or snapshots in the environment.
List indexes
Provides an overview of every active Pinecone index available to the system.
Query vectors
Performs similarity searches, returning vectors and metadata that match a given query.
Frequently Asked Questions
How do I use Pinecone with my AI agents to search my knowledge graph? +
You simply ask your agent what you want to know. The MCP handles the complex steps, like running query_vectors, and returns the most relevant data chunks right in your chat window for immediate context.
Can Pinecone help me manage my stored vector snapshots? +
Yes. You can list all existing collections using this MCP to see every snapshot you've kept, and then use the tools to archive or delete old data safely.
What if I need to check how full my index is right now? +
You just ask your agent to pull the usage statistics. It runs get_index_stats and tells you exactly how many vectors are stored and what percentage of capacity remains.
Is Pinecone MCP good for developers building prototypes? +
It's excellent for prototyping. You can test core endpoints, like retrieving specific records using fetch_vectors, directly within your development workspace without writing a single line of setup code.
Does Pinecone MCP let me delete data if something goes wrong? +
Yes. If you need to clean up or remove outdated information, the MCP provides tools like delete_vectors to ensure accurate and surgical removal of specific records from your index.
Can the AI execute raw vector similarity searches? +
Yes, absolutely. Once you supply the raw semantic embedding coordinates (normally a float array generated previously), the LLM can funnel it through the query_vectors tool. The Pinecone DB will process this and return the top-K closest vector matches along with embedded metadata.
How do I check my remaining vector storage capacity? +
It's extremely simple. Just ask the connected AI agent to 'Get the index stats'. It will internally call get_index_stats against the specified index namespace, returning total vector count and physical dimensionality limits to your chat window.
Is it safe to delete vectors dynamically using the chat terminal? +
Yes, but with standard precautions. The delete_vectors tool operates exactly as the official SDK. As long as you maintain clear contextual scopes and ID filtering in your prompts, the execution is purely deterministic and secure.
