Summary
mcp__as the MCP tool-name prefix for native Anthropic OAuth requests.tool_useresponses back into Hermes tool calls.Why
Claude Code's Anthropic OAuth tool protocol uses a double-underscore MCP marker, for example:
Hermes was previously emitting a single-underscore marker on the native Anthropic OAuth path:
That can make Hermes OAuth tool requests diverge from the Claude Code-compatible shape even though the request is otherwise using Claude Code/OAuth beta headers. Using the same
mcp__marker makes the OAuth tool schema consistent with Claude Code-style MCP tool naming.This PR is intentionally scoped only to tool-name compatibility. It does not claim to change Anthropic account/billing behavior such as extra-usage gating.
