The double-underscore prefix swap fixed bare native tools but SKIPPED tools already named mcp_<server>_<tool> (real MCP servers, e.g. mcp_linear_get_issue): they went on the OAuth wire single-underscore and still tripped Anthropic's third-party billing classifier -> HTTP 400 'extra usage, not plan limits'. Verified empirically against a live Max subscription: a single mcp_ tool flips the whole request to the extra-usage lane; mcp__ is accepted. - build_anthropic_kwargs: promote ANY leading single-underscore mcp_ to mcp__ (bare names -> mcp__name; mcp_<server>_<tool> -> mcp__<server>_<tool>), never double-prefixing an already-mcp__ name. Same for tool_use blocks in history. - normalize_response: reverse the mcp__ wire name back to whichever original the registry knows — the single-underscore mcp_<server>_<tool> form for MCP server tools, or the bare name for native tools — preferring a name that already resolves natively. - Tests rewritten to assert the invariant: ZERO single-underscore mcp_ names reach the OAuth wire, and the mcp__ round-trip resolves back to the registered name for both native and MCP-server tools. Builds on liuhao1024's mcp__ prefix commit (cherry-picked). Closes the MCP-server gap that left any session with an MCP server configured still billing to extra usage. |
