tengu_mcp_listen_reopen_park_tuning
A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.233, including the newest one read.
What it is
A flaky MCP server that keeps dropping event streams now gets a pause instead of endless instant reconnects.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.233.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.233 – 2.1.243 11 releases | in the build | — | null |
A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.
Gate readings

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
