Termalin Web does not always answer

Over the last week it answered 98.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

sftp

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

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 unix-socket via `sudo mysql`, redis-cli, mongosh, sqlite3) — so no database password is needed or stored anywhere. Read-only by default: only SELECT/SHOW-style statements run unless allowWrites is set (full-access keys only). SQL engines return CSV/TSV with a header. For MongoDB pass a shell expression, e.g. db.products.find({}).limit(20).toArray().

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.

generate

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.

hosts

hosts_list

List the servers reachable through Termalin (your tunnel agents). Returns id, name, whether the server is online, and the default login user. Use the id with ssh_exec.

ssh

ssh_exec

Run a single shell command on one of your servers and return its combined output. Runs keyless over Termalin's tunnel — no SSH key, and the server needs no open inbound port.

Termalin Web — questions

Answers built from our own checks of this server.

What can Termalin Web do?

It exposes 8 tools, read directly from the server on our last check. Among them: data_query, data_tables, generate_password, hosts_list, sftp_list, sftp_read and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Termalin Web mostly used for?

Its tools cluster around sftp and data. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Termalin Web working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 236 ms. The bar chart above shows every period we have measured.

How do I connect Termalin Web?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Termalin Web need an API key?

No. Termalin Web completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Termalin Web?

It answers our handshake in 236 ms on average, which is faster than 63% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
