On 2026-10-19 the server answered initialize and tools/list without a sign-in. First answer in 223 ms.

• Whether its tools do the product's job has not been judged yet.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• hosts_list

  List the servers reachable through Termalin (your tunnel agents). Returns id, name, whether the server is online, the user commands run as, when it was last seen, its country, and ownerNote — what the owner wrote about that server for you…

• generate_password

  Generate a strong random password — handy when creating a user or setting a password on a server. Returns the password only; nothing is stored.

• ssh_exec

  Run a single shell command on one of your servers and return its combined output and exit code. Runs keyless over Termalin's tunnel — no SSH key, and the server needs no open inbound port. Each call is a fresh shell (cd does not persist…

• ssh_exec_many

  Run the same shell command on several of your servers at once and return each server's output and exit code. Use it to compare or check a fleet (disk space, versions, a service's state) in one call instead of one call per server. Up to 10…

• job_start

  Start a long-running shell command on a server in the background and return a job id right away. Use it for anything that can take more than about a minute — package installs, builds, backups, migrations, large downloads. The job keeps…

• job_status

  Check a background job started with job_start: whether it is still running or finished (with its exit code), when it started, and the last lines of its output.

• job_stop

  Stop a background job started with job_start (asks it to terminate, then forces it after two seconds). Does nothing if the job already finished.

• job_list

  List the recent background jobs on a server (newest first): id, state, start time and the command.

• server_metrics

  Numbers Termalin's monitoring collects from the user's servers every minute, without running anything now: CPU, memory, disk, load, network, the busiest processes, failed services, containers, certificates. Without `host`: one line per…

• alerts_list

  What Termalin's monitoring says is wrong with the user's servers right now (disk filling up, memory or load pinned, a failed service, a restarting container, a certificate about to expire, a server offline), plus what cleared in the last…

• sftp_list

  List a directory on one of your servers over SFTP. Returns each entry's name, whether it's a directory, size and modified time. Runs keyless over Termalin's tunnel, like ssh_exec.

• sftp_read

  Read a text file from one of your servers over SFTP and return its contents. Files over 512 KB or non-text (binary) files are refused — use ssh_exec (e.g. sed/tail) for those.

• sftp_write

  Create or overwrite a text file on one of your servers over SFTP. 'content' is written as UTF-8. Capped at 512 KB; for binary uploads use a terminal/scp instead.

• data_query

  Run a database query on one of your servers — passwordless. It executes the engine's own client on the host over Termalin's keyless tunnel, using the database's local trust (Postgres peer auth via `sudo -u postgres`, MySQL/MariaDB…

• data_tables

  List the tables / collections / keys of a database on one of your servers — passwordless, over the same local-client path as data_query.

• data_schema

  Describe one table of a database on one of your servers: its columns with type, whether they can be empty, default value and primary key. Call it before writing a query against a table you have not seen. Works for postgres, mysql, mariadb…
