v0.29.0

Changed

• discover_tools renders callable signatures by default. The domain-listing, group, and keyword-query modes now return each tool as a Python-style signature (name(arg: type, ...)) instead of the JSON schema summary, so a caller can go straight to execute_tool without a get_tool_schema round-trip; format="schema" returns the previous JSON summary, and the no-argument domain summary is unchanged (always JSON). The server's InitializeResult instructions now advertise the two-step discover_tools() -> execute_tool() workflow, offering get_tool_schema() only when a signature is not enough. (#85)

Fixed

• infer_group recognises {group}_{action} tool names without a domain prefix. Previously every tool whose name did not start with its registered domain prefix fell into the "general" group, making group_overrides unreachable and discover_tools(group=...) useless for registries whose names are {group}_{action}-shaped (e.g. query_run_query under domain snowflake_mcp, now group query). After the existing domain-prefix branch, the group is the first _-segment; a single-segment name stays "general", and domain-prefixed names are unchanged. Deployment note: on a registry whose tool names are {group}_{action}-shaped under a mismatched domain, groups change from "general" to the first segment at this release — re-check group filters and group_overrides keyed on "general".
