Myriade

List databases configured in Myriade (paginated, sorted by name). Returns paginated database connections with their IDs, names, engines, and descriptions. Use the database ID with other tools.

Get detailed information about a specific database connection. Returns information about the database including its name, engine type, description, write mode, and any AI memory notes.

List tables in a database (paginated, sorted by database/schema/name). Returns a flat, paginated list of tables. Each item has database_name, schema, and name fields.

Get the column-level schema for a specific table. Returns column names, data types, and descriptions for the table. Raises if the user has no access to the table under governance.

Execute a read-only SQL query against a database. Write operations (INSERT, UPDATE, DELETE, DROP, etc.) are blocked. Returns up to 50 rows of results with column metadata. Successful queries are saved in Myriade; the response's `query_id` can be replayed later with myriade_get_query_results without

Re-execute a saved Myriade query and return fresh results. The query's SQL always re-runs under the caller's governance policies (table permissions, column masking) — results are never served from Myriade's cached snapshot. Prefer this over myriade_query for recurring metrics (dashboards, cockpits

Get sample rows from a table to understand the data. Returns a random sample of up to ``limit`` rows (max 20).

Search the data catalog for tables, columns, or terms by name/description. Uses fuzzy matching and full-text search. Keep queries short (1-2 words) for best results.

Get detailed information about a catalog object (table, column, schema, or glossary term — assets and terms share one id space). Returns the asset's description, tags, status, columns (for tables), sample data, parent hierarchy, and activity feed; for a glossary term, its definition, synonyms, rela

Update a catalog asset's documentation (requires edit rights). - ``description`` replaces the existing description (auto-sets status to "draft" if status is null). - ``tag_ids`` replaces all tags (accepts names or UUIDs; auto-creates missing tags). - ``status`` is "draft" (needs review) or "pub

Propose a catalog change for the data team to review (no edit rights needed). Creates a reviewable suggestion routed to the asset's reviewers. Does NOT change the published catalog until approved. Use this instead of ``myriade_update_asset`` when you lack edit rights or are not confident enough to

Ask a natural language question about a database using Myriade's data analyst agent. The agent will explore the database schema, search the catalog, run SQL queries, and analyze the results to answer your question. Use this for complex analytical questions that require multiple steps; for simple sc
