35 of 35 tools
Documented tools (35)
From project documentation. A server handshake does not verify each tool’s description or behavior.
apply_patch
Apply or check a unified diff with git apply
audit_tail
Read the local bridge audit tail
bridge_status
Runtime identity, paths, permissions context, shell, audit mode, Codex binary, focus policy, and background-Chrome status

Lease an idle tab from the persistent MDB group and open a URL without creating a new tab

Concurrency.
The session cap is taken, not merely checked, so concurrent ptystart calls cannot exceed it.
Containment.
See SECURITY.md — ptyclose reports leaderGroupGone, ttyProcessesKilled and uncontainedPids separately, and containmentVerified is true only when nothing survived.
fs_list
Recursive or non-recursive directory listing
fs_manage
mkdir, remove, move, copy, chmod, or symlink
fs_read
Read text or base64 with offset pagination
fs_stat
lstat metadata and symlink target

pty_signal

pty_start

Retention.
Each session keeps the last MACDEVBRIDGEPTYRINGBYTES of output in a fixed ring; ptyread reports lostBytes when a cursor falls behind it.

Run any foreground shell command, optionally with cwd, env, stdin, timeout, and output cap
shell_job_kill
Signal a background process group
shell_job_list
List persistent job metadata
