Myriade MCP Server

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 schema lookups or direct SQL, prefer the other tools. Note: the agent has access to catalog write operations (create/update assets, tags, terms) — it may modify catalog state to record findings. Use myriade_query directly for strictly read-only inspection. Requires AGENTLYS_PROVIDER and the corresponding API key (e.g. AGENTLYS_PROVIDER=anthropic + ANTHROPIC_API_KEY).

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.

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): the SQL stays governed in Myriade instead of travelling through prompts. Write statements are blocked. Returns up to 50 rows with column metadata, same shape as myriade_query.

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.

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.

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.

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 resending SQL.

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, related terms, and activity feed.

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 write directly.

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.

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 "published". Only use "published" with high confidence. Use ``myriade_request_catalog_change`` instead when you lack edit rights or are not confident enough to write directly.
