claude-presence v0.4.0 adds semaphore-style locks for parallel Claude Code sessions

claude-presence v0.4.0 is a minimal MCP server that helps multiple Claude Code sessions on the same machine coordinate with each other.

It provides:

presence tracking: who is working on what, and on which branch
cooperative named locks for shared resources like CI, ports, and staging databases
an inbox for messages between sessions
local SQLite storage with no daemon, no network, and no telemetry
MIT licensing

The new v0.4.0 release adds counted locks (semaphores) for cases where several agents can share a resource up to a limit. Example:

text

resourceclaim { resource: "cpu-heavy", capacity: 3, wait: true }

That lets up to three sessions run heavy tasks concurrently, with additional requests queued FIFO and notified when a slot opens. Capacity is fixed once the resource is held, and existing databases migrate automatically.

Other recent additions include:

self-hosted team mode with HTTP transport, token auth, and read/write/admin roles
targeted notifications surfaced at the next prompt
smarter locks with wait queues, renewal heartbeats, and branch-collision warnings
a live CLI dashboard, inbox threading, and dead-session cleanup
