Test that a Docker container is reachable and return its identity.

Read a UTF-8 text file from a Docker container. offset and limit select a 1-based line range; limit=0 means unlimited. Defaults to first 200 lines.

Write UTF-8 text content directly to a file inside a Docker container (creates or overwrites; use append=true to append instead).

Create a directory (and parents) inside a Docker container, equivalent to mkdir -p.

Read a file from a Docker container and return it as an MCP image. Supports common raster formats.

List a directory inside a Docker container with file metadata in ls -lAh style.

Search text files recursively inside a Docker container with ripgrep, falling back to grep. Output format is file:line:match.

Apply a unified diff inside a Docker container. Tries apply_patch (strip=0 only), then git apply, then patch. Supports dry-run and strip level.

Delete a file or directory inside a Docker container. Directories require recursive=true.

Execute an intentional shell command inside a Docker container. Supports stdin, cwd, env, custom output limit, and acceptable exit codes. Set background=true to run a command detached and get a job_id; stdin is not allowed for background jobs. Use docker_exec_result to poll/wait and docker_exec_kill to stop or clean up.

Check the status and output of a background job started with docker_exec background=true. Optionally wait until it exits.

Send a signal to a background job started with docker_exec background=true. Optionally remove the job log directory.

Start a command inside a Docker container with a TTY allocated, for programs that prompt for input (sudo password, y/N confirmations, setup wizards, REPLs). Waits until output goes quiet (likely waiting for input) or the process exits, then returns the output so far plus a session_id. If the command finishes without prompting, the session is closed automatically and there is nothing further to do. Otherwise, use docker_interactive_input to reply or poll, and docker_interactive_close when finished. Idle sessions auto-expire after 10 minutes.

Send a line of input to a running docker_interactive_exec session (e.g. answer a sudo password or y/N prompt), or just poll for more output if input is omitted. Returns newly produced output and status.

Kill and remove an interactive Docker session started with docker_interactive_exec.

List currently open interactive Docker sessions.

Copy a local file or directory into a Docker container (analogous to docker cp local container:path).

Copy a file or directory from a Docker container to the local machine (analogous to docker cp container:path local).

No-op for Docker: the transport does not keep a persistent connection. Always succeeds.
