Common questions
Is Db Planner safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

DB Planner MCP server
Hosted MCP server for DB Planner that lets any MCP client edit database schemas (DBML/SQL), Mermaid diagrams and board layouts. OAuth sign-in, nothing to install.
https://api.dbplanner.io/mcpThis repository is documentation. The server is built into the DB Planner API and there is no code to run: add the URL to your client, sign in once in the browser, and your agent has 38 tools over your projects.
What is DB Planner
DB Planner is a collaborative database design tool. You write schemas in DBML or import SQL dumps (PostgreSQL, MySQL and SQL Server), sketch diagrams in Mermaid, and lay both out on a shared board that renders relationships, notes and drawings in real time. The template marketplace is where published schemas are shared.
Connect
Claude Code
claude mcp add --transport http db-planner https://api.dbplanner.io/mcpCursor and other clients with a JSON config
{"mcpServers": { "db-planner": { "type": "http", "url": "https://api.dbplanner.io/mcp" } } }
The url is the same everywhere; the type value is not. Claude Code's .mcp.json takes http as above, Cursor's .cursor/mcp.json needs no type at all, and Cline's mcp.json takes streamableHttp. Check your client's documentation for its remote-server shape.
Claude.ai and Claude Desktop
Settings, then Connectors, then Add custom connector. Paste the URL. Leave authentication on "Always required" and the OAuth client on "register one automatically". No headers.
MCP Inspector
npx @modelcontextprotocol/inspectorClick Add Servers, then fill in the form: server ID db-planner, transport streamable-http, URL https://api.dbplanner.io/mcp. Add it, switch it on, and the consent screen opens in the browser.
On every client the first tool call opens the DB Planner consent screen. Sign in, pick the scopes, and you are connected. No password or API key is stored in the client configuration. An agent setting this up on your behalf should read llms-install.md.
Authentication
The endpoint is protected by OAuth 2.1 with PKCE. Discovery is standard, so clients configure themselves from the URL alone:
https://api.dbplanner.io/.well-known/openid-configurationhttps://api.dbplanner.io/.well-known/oauth-protected-resource- Dynamic client registration at
https://api.dbplanner.io/connect/register, for both public clients (token_endpoint_auth_method=none) and confidential ones (client_secret_post,client_secret_basic)
Two scopes are the whole permission model, and the split is enforced on the server, not in the client:
| Scope | Grants |
|---|---|
dbplanner:read | Every read tool. Always granted, because the endpoint requires it. |
dbplanner:write | The mutating tools, checked per tool. Also covers publishing to the public marketplace. |
MCP clients ask for both. Read is always granted, and write is a checkbox on the consent screen, on by default. Turning it off means the token is issued without write even though the client requested it, so a read-only connection is a real guarantee rather than a client-side courtesy.
Clients also request offline_access. That is a session mechanism rather than a permission: it yields a refresh token so the connection survives token expiry, and it is granted whenever asked.
A tool never sees more than the signed-in user can see in the app: organization and project roles are resolved from the token's subject and enforced by the same services the web app uses.
Tools
Every tool carries a title, a read-only or destructive hint, an openWorldHint of false, a description on every parameter and an output schema, so clients can run reads without confirmation prompts and read structured results instead of parsing text.
| Group | Read | Write |
|---|---|---|
| Session | whoami, get_public_profiles | |
| Organizations | list_orgs, get_org | create_org, rename_org, delete_org, upsert_org_member, remove_org_member |
| Projects | list_projects | create_project, update_project, delete_project, upsert_project_member, remove_project_member |
| Documents | list_documents, list_diagrams | create_document, update_document, delete_document, reorder_documents, set_table_color |
| Board | get_board, get_board_image, list_tables, list_drawings | update_board, draw, draw_shape, erase_drawings, add_board_image |
| Marketplace | browse_templates, get_template, list_my_listings | use_template, publish_listing, update_listing, unpublish_listing |
A few things worth knowing before an agent calls them:
- Design lives in documents, never on the board. Tables, columns, references, enums, classes and flowchart steps are derived by parsing a document, so the design changes through
create_documentandupdate_documentand the board follows. There is no tool that creates a table directly. - `get_board_image` renders the board to a PNG so the model can look at a layout rather than infer it from coordinates. Pass
format='svg'for the vector source as text. - `draw` and `draw_shape` are the drawing tools. Ink and arrows are one tool with a
kind; rectangles, diamonds and ellipses, with optional bound text, are the other. Both mint ids and round coordinates the way the app does. Free text on its own, groups and links go throughupdate_board. - `update_board` takes a partial delta. Send only the card ids you are changing; a null value deletes one. It is the same merge contract the app uses, so an agent moving one card does not clobber a collaborator's layout.
- Publishing is creator-only, and no tool takes a price. Only the person who created a project may list it, and a listing published through MCP is always free. Pricing requires Stripe onboarding that nobody can do on someone's behalf.
