Supabase's server reaches well past the database into functions, logs and branches, and every safe setting it needs exists, though none of them is the default.
Best for: Developers building on hosted Supabase who want an agent to manage schema, functions and debugging, ideally on development branches.
Price: Server is free. Supabase Free allows 2 active projects, paused after a week idle; Pro from $25/month with $10 compute credit; Team $599. Branches $0.01344/hour.

The database server to build production agents on, because it lets you replace open SQL with queries you wrote, though its network defaults assume more care than most people take.
Best for: Teams that work across several databases or want to build controlled database tools for production agents.
Price: Free and Apache-2.0 licensed; you run it yourself. Database, query and Google Cloud hosting costs are separate.

Read-only examples, confirmation prompts and injection-wrapped results make this a careful default for MongoDB, provided you trim its 53 tools.
Best for: Teams on MongoDB or Atlas who want agents to explore data and manage clusters with safety defaults already in place.
Price: Server is free and Apache-2.0 licensed. Atlas M0 is free with 512 MB; Flex costs $8–$30 a month; dedicated clusters start at $0.08/hour (M10).

Branch-tested migrations and URL-pinned read-only grants make this a safe way to let an agent near Postgres, in development, which is where Neon says it belongs.
Best for: Developers on Neon Postgres who want an agent to manage projects, branches and schema changes during development.
Price: Server is free. Neon Free: 100 projects, 100 CU-hours a month and 1 GB storage per project. Launch $0.106/CU-hour and Scale $0.222/CU-hour, plus $0.35/GB-month storage.

A small, well-designed SQL gateway for agents, provided it connects as a read-only database user, since its own read-only mode has already been bypassed twice.
Best for: Developers who want an agent to explore and query several SQL databases with one small, configurable server.
Price: Free and open source (MIT). Bytebase sells a separate enterprise product with approval flows, masking and audit logs.

Three tools and a read-only default make this a safe first database server for an analytics agent, provided you cap result sizes yourself.
Best for: Data teams who want an agent to answer questions from ClickHouse with safe defaults.
Price: Free and Apache-2.0 licensed. ClickHouse Cloud is billed separately (Enterprise compute from about $0.33 per 8 GiB unit-hour) and offers a 30-day trial with $300 of credits.

Governance done properly for agents on Snowflake, paid for in admin hours and warehouse credits rather than a licence fee.
Best for: Snowflake customers who want governed agent access to warehouse data and Cortex services under existing roles.
Price: No separate MCP fee is published; tool calls run on your Snowflake warehouses and Cortex services, which bill as usual.

Broad, faithful coverage of Redis for a local agent, but with no remote transport and no read-only switch it belongs next to a development database.
Best for: Developers who use Redis for caching, queues or vectors and want agents to read and write that data.
Price: Free and MIT-licensed. Redis Cloud has a free 30 MB database; Essentials from $5/month; Pro from a $200/month minimum.

A tidy, local-first memory for agents that already sit next to Qdrant, deliberately too small to be a general interface to the database.
Best for: Teams already running Qdrant who want a simple, self-hosted semantic memory or snippet store for their agents.
Price: Free and open source (Apache 2.0). Qdrant is free to self-host; Qdrant Cloud has a free single-node tier (0.5 vCPU, 1 GB RAM, 4 GB disk), usage-based Standard and a Premium tier with a minimum spend.

Lets an agent run the statistics instead of estimating them, from a capable project almost nobody uses yet.
Best for: Analysts and developers who want an agent to run real statistics on local data.
Price: Free and open source under Apache 2.0.
