# Protocols Primer

Protocol primers explain how to authenticate, select a Workspace, initialize a
client, handle errors, and use Flight SQL. The reference itself is organized by
product resource rather than duplicated into HTTP, MCP, and SDK trees.

Each operation page combines the native OpenAPI contract, available SDK
examples, and its exact MCP tool mapping when the operation explicitly opts in.
HTTP and SDK identifiers remain unchanged while each MCP tool owns a concise,
curated handle. The [protocol terminology ledger](/project/agents/skills/services/protocols/terminology)
records their relationship to current product language.

Use the language SDK primers for Workspace operations. Use the
[SQL primer](/protocols/sql) for the shared query model, data catalog, and pool
addresses; its examples show the supported SDK path first and keep Flight SQL
wire details in the advanced reference.
