* fix(mcp): a refused tool call is audited as denied, not ok (BUG-3879) A failed tool call answers the /mcp POST with 200 and an error result, so the audit middleware, which classified only the transport status, wrote result_status=ok for every refused write. MCPAuditLog now installs an outcome sink on the request context; a tool-handler middleware on every MCP server pad builds records a failed result's error code (and details.reason) into it. permission_denied, auth_required and rate_limited are denied; any other failure is an error; the code is the error_kind. Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * test(mcp): unit rows for the tool-outcome sink, codes and middleware order (BUG-3879) Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * docs: the MCP audit status is the call's outcome, not the transport's (BUG-3879) Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * fix(mcp): a JSON-RPC error inside a 200 is audited too, via an OnError hook (BUG-3879 hunter r1 M1) mcp-go refuses an unknown tool, and answers a missing resource or prompt, before the tool-handler middleware runs, so those calls were still audited as ok. Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * test(mcp): a failed tools/list audits as error; the prose names what OnError cannot see (BUG-3879 r2) Lead ruling R2 pins the unscoped hook; hunter r2 L1 narrows the claim: a message rejected before method dispatch never reaches OnError. Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * test(mcp): a refused write's audit kind carries the reason BUG-3864 added (BUG-3879) After rebasing onto #2218 (BUG-3864), the 403s for a read-only token's write and a viewer's write carry details.reason, token_scope and role. recordToolOutcome writes error_kind as <code>:<reason> whenever a reason is present, as designed, so the two transport rows now expect permission_denied:token_scope and permission_denied:role. On the old base those 403s carried no reason, which is what the rows had pinned. Claude-Session: https://claude.ai/code/session_016Msqj8nRQUNbgdsXxhBBVR * fix(mcp): an unverified email's refused call is audited as denied (BUG-3879 r4) Since BUG-3864, a write refused because the account's email is unverified answers with its own MCP code, email_not_verified, rather than permission_denied. classifyMCPToolOutcome only knew the older three refusal codes, so after the rebase onto #2218 that refusal was audited as error. It is denied now, as the classifier's own comment and this bug's contract already said. The plan and member limits stay errors (BUG-3894 owns that policy). The unit rows that paired permission_denied with an email_not_verified reason described a payload the server never sends; they now use token_scope, a reason it does send, plus a row for the real code. A new transport row drives an unverified owner's write on the Cloud fixture and requires a denied row. docs/api.md and the metric's Help text name the code.
