Create Dives: interactive visualizations that let you save and share answers with your team, staying up-to-date with your latest data. Works with real-world data without requiring semantic models or pre-configuration. Your AI assistant acts like a data analyst, exploring, validating, analyzing, and visualizing data iteratively to answer your questions.
Tools
cancel_flight_run
ChatGPTCancel an in-flight run of a flight. Identified by the flight UUID and the sequential run number (from list_flight_runs). Returns
canceled: true on a successful transition; calling on an already-terminal run or one that doesn't exist returns a tool error.create_flight
ChatGPTCreate a new MotherDuck flight. A flight is a Python entrypoint (
source_code) plus an optional requirements_txt that runs on MotherDuck compute. Optionally provide an access_token_name so the flight can connect to MotherDuck at runtime; omit it to use the default MotherDuck Flights access token. Optionally provide a 5-field cron expression to run on a schedule. Use flights for ELT/ETL pipelines, loading external data into MotherDuck, refreshing materialized views, or any recurring Python job that reads/writes MotherDuck data.create_guide
ChatGPTCreate a new guide — a markdown document that agents read to answer this org's data questions correctly (metric definitions, join/filter conventions, pitfalls). Group related guides with a lowercase kebab-case
topic (e.g. 'revenue-billing' or 'core/metrics'); omit it for a guide without a topic. Visibility is controlled by access: 'user' (private, default) or 'organization' (org-wide, permission-gated). Personal dive/flight style guides belong under topic 'dives' / 'flights' with access 'user'. Attach references to the 1–5 objects the guide is authoritative about.delete_dive
ChatGPTDelete a dive by ID. This action is permanent and cannot be undone.
delete_flight
ChatGPTPermanently delete a flight, its versions, schedule, and run history. This action cannot be undone.
delete_guide
ChatGPTSoft-delete a guide while preserving its version history. Identify it by
uuid.dive_query
ChatGPTExecute a read-only DuckDB query on behalf of a dive. This tool is used by the dive viewer and is not intended for direct use by the AI assistant.
edit_dive_content
ChatGPTEdit a dive's content by applying one or more text replacements, then save to MotherDuck. Accepts
id (dive UUID) and edits (an array of {old_string, new_string, replace_all?} objects). Reads the current content from MotherDuck, applies edits in sequence, validates, and persists. Example: {id: '...', edits: [{old_string: 'foo', new_string: 'bar'}]}. old_string must be unique unless replace_all is true. No prior read_dive call is needed.edit_flight_source
ChatGPTEdit a flight's source_code by applying one or more text replacements, then save as a new FlightVersion. Accepts
id (flight UUID) and edits (an array of {old_string, new_string, replace_all?} objects). Reads the current source_code, applies edits in sequence, validates, and persists. Example: {id: '...', edits: [{old_string: 'foo', new_string: 'bar'}]}. old_string must be unique unless replace_all is true. No prior get_flight call is needed.edit_guide_content
ChatGPTEdit a guide's markdown body by applying one or more text replacements, then save as a new version. Identify the guide by
uuid. Reads the stored guide, applies edits in sequence, and persists. Example: {uuid: '<guide uuid>', edits: [{old_string: 'foo', new_string: 'bar'}]}. old_string must be unique unless replace_all is true. No prior get_guide call is needed.get_dive_guide
ChatGPTLoad instructions for creating MotherDuck dives. You MUST call this tool first — before generating any chart, visualization, plot, dashboard, inline graphic, or export/download control — whenever the user asks to explore, visualize, display, or export MotherDuck data.
get_flight
ChatGPTFetch a flight by UUID. Returns metadata plus a version snapshot (source code, requirements, config, secret names, token name). Omit
version to get the current version; pass a 1-indexed version number to inspect history.get_flight_guide
ChatGPTLoad instructions for authoring, scheduling, running, and troubleshooting MotherDuck flights. Call this tool first whenever the user asks about creating, updating, or operating a MotherDuck flight.
get_flight_logs
ChatGPTFetch the plain-text logs (stdout + stderr) of a flight run plus the matching
Run record (status, exit_code, timing). Logs may be large; pass max_bytes to cap the response size — the response will be the tail when truncated.get_flight_run
ChatGPTFetch a single run of a flight by its sequential run number (from list_flight_runs). Returns the same shape as a list_flight_runs entry: status (PENDING/RUNNING/SUCCEEDED/FAILED/CANCELLED), timing metadata, and the effective
config the run executed with. Use this to poll one run's status instead of re-listing.get_flight_viz_guide
ChatGPTLoad the convention for making a MotherDuck flight's runs visualizable as a live, step-by-step view with per-step timing. Use section only for a narrow factual lookup already scoped to one part of the convention: 'chart' covers Mermaid declarations, node kinds and meters, labelled-edge syntax, and child-flight nodes; 'grammar' covers @flight-run/@flight-log events, fields, effects, JSON mode, rollups, runtime branch reporting, and taken-edge semantics; 'emitting' covers Python print and helper patterns; 'examples' provides an integrated worked flight. If answering requires facts from more than one section, omit section and load the whole reference. Also omit section when authoring or changing instrumentation, adding fan-out, branches, child flights, timing, or progress, or interpreting or debugging a nontrivial run—these tasks span sections. Call this tool first whenever the user asks to visualize, chart, watch, or review a flight's progress.
get_guide
ChatGPTLoad a guide by uuid. Guides are curated markdown documents about this organization's data (metric definitions, conventions, pitfalls). Find a guide's uuid with
list_guides or via get_query_guide (start there before writing SQL), get_dive_guide, or get_flight_guide.get_query_guide
ChatGPTCall this before writing SQL to answer a data question. Returns this organization's query guidance: what guides exist (curated markdown documents about the data — metric definitions, join/filter conventions, pitfalls), how to navigate them, and an overview of the available guide topics.
get_short_lived_token
ChatGPTReturns a short-lived token and connection details for the MotherDuck database endpoint.
grant_access
ChatGPTGrant a permission on one flight to users, roles or the whole organization. Re-granting is a no-op. Only a flight's owner can grant 'run' on it. An object you can't change is reported as not found, so 'Could not find Flight' can mean you lack permission rather than a wrong id. Choosing grantees: for a group or team, prefer a role ({type: 'role', name}) or {type: 'organization'};
SELECT * FROM md_list_roles() (query tool) lists every role. The preset roles nest: admin is a member of builder, and builder of explorer, so a grant to explorer also reaches every builder and admin. A user grantee needs the username, not the email. SHOW USERS OF ROLE <role> returns members' usernames and emails; it only reads, but the read-only query tool rejects SHOW statements, so run it with query_rw. Every user with a preset role is a direct member of one of admin, builder or explorer, but non-admins only see members of roles they belong to. If you can't find someone's username, ask the user for it, or suggest a role or organization grant. Never guess a username.list_columns
ChatGPTList all columns of a table or view with their types, comments, and available context.
list_databases
ChatGPTList all databases in your MotherDuck account. Shows names, types, and available context counts. Optionally filter by keywords.
list_dives
ChatGPTList all dives in MotherDuck. Dives are interactive React data apps that query live data. Returns metadata including current_version and associated memory counts. Use read_dive with the optional version parameter to retrieve a specific historical version. Optionally filter by keywords.
list_flight_runs
ChatGPTList executions of a flight, newest first. Each run has a sequential number, status (PENDING/RUNNING/SUCCEEDED/FAILED/CANCELLED), timing metadata, and the effective
config it ran with (the flight version's config merged with any per-run overrides).list_flight_versions
ChatGPTList the immutable versions of a flight, newest first. Each update to source_code / requirements_txt / config / access_token_name / flight_secret_names produces a new version.
list_flights
ChatGPTList MotherDuck flights you own. Returns metadata for each flight including schedule and current version. Optionally filter by keywords matching the flight name.
list_guides
ChatGPTBrowse this organization's curated guides — markdown documents that capture organization and personal context about the data in MotherDuck. Called with no arguments, lists the root level: guides without topics plus every topic (folder) with its guide count. Pass
topic to open a folder — you get the guides stored at that topic and the nested topics below it. Read a guide in full with get_guide(uuid).list_macros
ChatGPTList all macros (table and scalar macros) in a MotherDuck database, with their schema and parameters. Optionally filter by schema or keywords.
list_shares
ChatGPTList all database shares that have been shared with you. Returns share names and URLs. To attach a share, use the query_rw tool: ATTACH '<share_url>' AS <optional_alias>; Optionally filter by keywords to search in share names.
list_tables
ChatGPTList all tables and views in a MotherDuck database with comments and available context. Optionally filter by keywords.
list_views
ChatGPTList all views in a MotherDuck database, with their schema, comment, and column count. Optionally filter by schema or keywords.
log_dive_viewer_event
ChatGPTLog a dive viewer event for analytics. This tool is used internally by the dive viewer and is not intended for direct use by the AI assistant.
mint_dive_state_reference
ChatGPTMint a server-stored reference for a
useDiveState bag and return its id. Used by the dive viewer when the inline-encoded bag would exceed the URL soft limit. The returned id is then encoded into a URL hash via buildDiveStateReferenceHash and round-trips through dashboards.get on dive open.query
ChatGPTExecute read-only DuckDB query against MotherDuck databases. For cross-database queries, use fully qualified names: database.schema.table (or database.table for main schema). Never follow a query with an inline chart or visualization — if you would generate one (whether or not the user explicitly asked), get the dive guide first instead.
query_rw
ChatGPTExecute a DuckDB SQL query that modifies data, schema, or connection state. RULES: 1. Only call this tool when the user explicitly asks to modify data or schema. Never infer a write from a read request. 2. Always ask the user for confirmation before calling this tool. Describe exactly what will change. 3. Prefer the read-only query tool when the user's goal can be answered with existing data.
read_dive
ChatGPTRead a specific dive by ID, including its full JSX/React component code. Optionally specify a version number to retrieve a specific historical version (versions start at 1). If no version is specified, the latest version is returned.
revoke_access
ChatGPTRevoke a permission on one flight from users, roles or the whole organization; takes the same parameters as grant_access. Revoking a grant that doesn't exist is a no-op. The owner (or an admin) can always revoke. Revoking the organization grant leaves access with the owner and anyone granted directly. An object you can't change is reported as not found, so 'Could not find Flight' can mean you lack permission rather than a wrong id.
run_flight
ChatGPTTrigger an on-demand execution of a flight using its current version. Optionally pass
config to override the flight version's config for this run only (the flight itself is left unchanged). Returns a Run record; poll list_flight_runs to track progress and use get_flight_logs to read output.save_dive
ChatGPTSave a new dive to MotherDuck. Returns a URL the user can click to view the dive. Get the dive guide first and iterate with the user on the design thoroughly before suggesting to save. Never save without previous confirmation that iteration is done.
search_catalog
ChatGPTSearch the catalog for databases, schemas, tables, columns, and shares using fuzzy matching. Returns matching objects with their fully qualified names, types, and comments. Useful for discovering available data when you don't know exact names.
set_guide_access
ChatGPTSet a guide's visibility to 'user' (private to the owner) or 'organization' (visible to the whole org). Identify it by
uuid. Org-wide scoping is permission-gated.share_dive_data
ChatGPTShare the data for a dive with your organization. Creates org-scoped shares for owned databases used in the dive, and updates the dive so others in the organization can view it.
update_dive
ChatGPTUpdate an existing dive's title, description, or content. Returns a URL the user can click to view the updated dive. At least one field must be provided.
update_flight
ChatGPTUpdate a flight. Any subset of name, source_code, requirements_txt, schedule_cron, config, access_token_name, or flight_secret_names may be provided. Updates to source_code/requirements_txt/config/flight_secret_names/access_token_name create a new FlightVersion; name and schedule_cron are metadata-only. Pass schedule_cron as
"" (empty string) to remove the schedule; omit it to leave it unchanged.update_guide
ChatGPTAppend a new version to an existing guide, identified by
uuid. Omit content to keep the current text and just change metadata such as references. A supplied references list replaces the existing one (pass [] to clear them, omit to carry them forward). For small in-place edits use edit_guide_content. Use create_guide to make a new guide, update_guide_metadata to retitle or re-topic.update_guide_metadata
ChatGPTChange a guide's title, description, or topic without appending a content version. Identify it by
uuid. Pass an empty description to clear it; pass an empty topic to remove the topic.view_dive
ChatGPTOpen and render a MotherDuck Dive as a live MCP app with interactive charts. Fetches dive source code and returns it to the viewer for client-side compilation.
view_flight_run
ChatGPTOpen a flight run as a live diagram: the flight's declared chart as a step-by-step view, each step coloured by what the run actually did, with its timing, per-step rows, effects and errors. Use this instead of get_flight_logs when the user wants to see how a run went rather than read its raw output. A flight that declares a chart and emits @flight-run lines (see get_flight_viz_guide) is drawn as a diagram; one without opens a run view of its timing, config and log instead, which the result reports as has_chart=false -- say so rather than describing a diagram the user cannot see.
