failed to insert mcp_writes audit row

Error message

failed to insert mcp_writes audit row

What it means

The SQLite INSERT into the mcp_writes audit table failed after serialization succeeded. This is logged as a warning and the record_write call continues — audit persistence is best-effort by design and must not fail the MCP tool call it is auditing. Typical causes: the database file is locked by another connection, the schema is missing/corrupted, or disk is full. The audit row for this write is lost.

Solutions

1. Check SQLite connectivity and locks — ensure only one process owns the audit DB or enable WAL/busy_timeout
2. Run the mcp audit schema init/migration to ensure the mcp_writes table matches the insert's columns
3. Free disk space or repair the audit database file if it is corrupted
