| Best for | - Developers who use Pinecone as part of their technology stack.
- Users who want to manage Pinecone projects and indexes from within AI coding assistants.
- Those needing to interact with Pinecone documentation or generate code based on configuration.
| - Teams already using ClickHouse who want AI assistants to access data directly.
- Scenarios requiring fast, read-only data queries and schema exploration.
| - Teams that want precise control over which database operations an AI can perform, rather than open arbitrary SQL execution
- Scenarios needing a unified MCP setup across multiple database engines
|
|---|
| Not for | - Users working with indexes without integrated inference, or requiring standalone embeddings, vector search, or assistant features.
- Scenarios where you need to provide AI assistants with context from your knowledge base (use Pinecone's Assistant MCP for that).
- Non-developer use cases or non-coding assistant environments.
| - Scenarios requiring write access to the database without explicit opt-in.
- Production environments with stringent security requirements that avoid default permission settings.
| - Lightweight cases that just want to run a few ad-hoc SQL queries without maintaining a tools.yaml config (a simpler single-database MCP may be a better fit)
|
|---|
| Required permissions | - Requires a PINECONE_API_KEY environment variable to access your Pinecone project.
- Allows AI tools to create, list, describe, and delete indexes (actions depend on tool set).
- Allows upserting and searching records, as well as cross-index search and reranking operations.
- Allows searching official Pinecone documentation (no API key needed).
| - Requires read-only access to ClickHouse database (default).
- Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
- Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
| - Database credentials (username/password/connection string) are supplied via env vars or config
- A tool's actual permission is whatever SQL statement is defined in tools.yaml — designed for least privilege, but misconfiguration can still over-expose access
|
|---|
| Risks and side effects | - API key exposure: ensure the key is kept secure and not committed to version control.
- Misoperations: AI assistants may accidentally create, modify, or delete indexes; authorize carefully.
- Cost implications: index operations and data usage may incur charges; monitor usage.
- Network dependency: requires access to api.pinecone.io; may fail behind firewalls.
| - If write access is enabled, AI might make unintended modifications.
- If DROP access is enabled, data deletion could occur accidentally.
- Credentials may be exposed via environment variables.
| - If tools.yaml defines SQL statements that allow unconstrained writes or deletes, the AI could accidentally modify data
- The prebuilt toolsets (--prebuilt) favor convenience and may expose broader query capability than a specific business actually needs — use a custom tools.yaml in production
