Module mcp_tool_names 

MCP tool-name parsing and building.

Pure string functions over tool name spellings, with no dependency on the tool system. This is the single home for MCP name shapes so the agent runtime, policy gates, and transcript display never fork the parsing.

MCP Tool Name Format

Canonical form is mcp::<provider>::<tool_name>. Model-visible form is mcp__<provider>__<tool>. Legacy form is mcp_<provider>_<tool_name>.

Constants

MCP_QUALIFIED_TOOL_PREFIX

The MCP tool name prefix used in model-visible form.

Functions

model_visible_mcp_tool_name

Build a model-visible MCP tool name from provider and tool name.

parse_canonical_mcp_tool_name
