Document result shapes and practical calls for all built-in actions,
including prerequisites, streaming workflows and compatibility limits.
Preserve existing interfaces and execution behavior, and verify the
catalog against action validation and representative responses.
Add structured results, optional keyword search and pagination, and runtime information with explicit connection checks. Preserve existing text responses and execution permissions.
Support request cancellation and transfer progress. Verify compatibility with the full CI suite and isolated MCP and HTTP integration tests.
Move database work off the main thread on Node.js 24 and improve message handling and runtime diagnostics.
Preserve migration, restart, and concurrency coverage with the async SQLite driver.
@snowluma/mcp gains execution alongside the read-only catalog: when SNOWLUMA_MCP_ENDPOINT is set it exposes query_action (read-only actions, readOnlyHint) and, in write mode, invoke_action (any known action, destructiveHint), proxied to a running OneBot instance over HTTP. Without an endpoint it degrades to docs-only. SNOWLUMA_MCP_MODE (docs|read|write) gates tool visibility AND is re-checked in execute(), so an unlisted tool cannot be called; unknown/legacy actions are non-invokable.
Read vs write is classified precisely at the source: defineAction/preset gain readOnly (default false = write, the safe default), flowed through describe() into the generated catalog snapshot. 58 actions are marked read-only by what their run() actually does -- name-traps like get_ai_record (publishes to the group), request_decrypt_key (returns a DB key), and download_file (arbitrary URL + disk write) stay writes.
The HTTP call is a ~20-line fetch bridge rather than @snowluma/sdk: the SDK's published dist is bundler-only ESM (extensionless imports) that native node cannot load, and the bin stays a plain tsc build.
onebot 332 tests pass (readOnly is metadata-only, no behavior change); mcp gains 21 tests for mode gating / read-write routing / envelope passthrough / error mapping. Full workspace typecheck clean; native node smoke verified.
