What you get that a built-in agent shell doesn't:
cd and env carry across
calls, and every command returns a structured result: split stdout/stderr,
exit code, duration, cwd.tail, head, grep, a char cap) keep a
noisy build from flooding the context window.Zero-install, with uv. Add this to your MCP client config:
{ "mcpServers": { "execkit": { "command": "uvx", "args": ["execkit-mcp"] } } }
Or install it and let execkit print the config for your client:
pip install execkit-mcp && execkit-mcp setup claude # or: cursor | gemini | codex | vscode | windsurf
Then execkit-mcp doctor checks your setup. More options (prebuilt binary,
cargo install, building from source) are in the Quickstart.
Status: early 0.x. The API may change between minor versions. Read
Limitations before pointing it at anything important.
execkit complements your agent's built-in shell or sandbox; it does not replace it. Use it when the agent needs to work on a remote host or inside a container, when you want a record of what ran, or when you want to undo file changes on a remote workspace.
The agent is the adversary. The LLM driving execkit can be prompt-injected by anything it reads, so execkit contains its own caller: a command passes the policy fence before it runs, secrets are redacted before output returns, and a changed SSH host key fails loudly instead of reconnecting into a MITM.

The agent gets session_create (local, ssh, or docker), session_exec,
session_list and session_destroy, plus session_checkpoint /
session_checkpoints / session_restore for remote undo.
State persists across calls, and every result is parsed, not scraped from a terminal:
// session_exec {"command": "cd /app && npm ci"} -> { "exit_code": 0, "cwd": "/app" }
// session_exec {"command": "npm run build"} // cwd is still /app
// -> { "stderr": "Error: Cannot find module 'webpack'",
// "exit_code": 1, "duration_ms": 3420, "cwd": "/app",
// "truncated": false, "timed_out": false }
Commands time out after 120 seconds by default (timeout_secs per call, up to
3600). On timeout execkit interrupts the command with Ctrl-C and returns
timed_out: true with exit code 124. The session keeps its cwd and env.
See crates/execkit-mcp/README.md for the operator
security settings (host-key verification, key dir, audit, session limits).
Set EXECKIT_MCP_AUDIT_DIR and every session is recorded. execkit-mcp watch
shows it live in the terminal, and execkit-mcp watch --serve --open opens the
read-only browser viewer shown at the top.

Old pins are not read. The first connection re-pins, or copy them over with
mkdir -p ~/.execkit && chmod 700 ~/.execkit then
grep -E '^[^ ]+ SHA256:' ~/.ssh/known_hosts >> ~/.execkit/known_hosts.
Old pins were keyed by bare host whatever the port: rewrite a line for a
non-22 port as [host]:port, or a later port-22 connection to that host fails
as a key mismatch./dev/null for every command, and pagers are set to cat.base64.timed_out: true and keeps the session,
instead of an error that closed it. ExecResult has a new timed_out field.a3f9-1_local instead of 1_local.SshConfig has a new connect_timeout field (default 15 s). Use
SshConfig::new.deny: ["curl"] blocks curl but not env curl, sudo curl or
sh -c curl. The real control is a least-privilege environment: run the agent
and SSH user with minimal rights./dev/null, so prompts, REPLs and editors do
not work. Use non-interactive flags (sudo -n, apt-get -y). Pagers default to
cat, but running less or vim directly hangs until the timeout and closes
the session. Shell history is off.nohup CMD > /tmp/job.log 2>&1 &) and poll the log.base64. Local sessions use bash.
