ECC_MEMORY_HARNESS must identify this MCP server with a lowe

Error message

ECC_MEMORY_HARNESS must identify this MCP server with a lowercase harness slug.

What it means

resolveServiceSecurity requires ECC_MEMORY_HARNESS (or an explicit harness option) to be a lowercase slug identifying the calling MCP client; it must match SLUG_REGEXP so per-harness namespacing stays safe. Missing, uppercase, or malformed values all fail here.

Solutions

1. Review the constraint in the error message, correct the input accordingly, and re-run.

When it happens

Trigger: Triggered when memory-mcp.mjs rejects the current invocation: ECC_MEMORY_HARNESS must identify this MCP server with a lowercase harness slug.

Common situations: Occurs while running scripts/memory-mcp.mjs with invalid arguments, missing flags, or a failing external dependency; the guard at scripts/memory-mcp.mjs:169 aborts the command with this message.
