MCP Router: protocols.stateless.toolsListTtlMs

toolsListTtlMs is the lifetime of a cached authorization-filtered stateless tools/list result.

• Type: Positive integer, in milliseconds
• Default: 30000

The result reports the same value as ttlMs. Cache keys bind the entry to the principal, policy/config revisions, protocol version, and relevant forwarded headers. A tool catalog or policy reload changes the revision and causes a new result to be produced.
