Analyzed 2,882 MCP tool calls across 242 conversations to identify systematic failure patterns. Fixes 39 actionable errors (7.5% error rate): - Default child/linked item project_id to parent's when omitted (31x mismatch) - Accept `query` as alias for `search` in search_repositories (3x errors) - Normalize `work_item_iid` -> `iid` for work item tools (11x errors) - Coerce JSON-stringified arrays for labels/assignees fields (2x errors) - Case-insensitive issue_type enum in update_issue (5x errors) - Skip weight widget for incident work items in create (4x errors) Includes scan-mcp-errors.py diagnostic script for ongoing analysis.
LLMs frequently send "true"/"false" strings instead of boolean values. Applied z.coerce.boolean() to all boolean fields across all schemas.
