File Relay missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 5

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

file

delete_file

Delete a relayed file before it expires. Requires the delete_token returned at upload.

get_file_info

Look up a relayed file by id or download URL: name, size, type, expiry and download link.

read_file

Read a relayed file's content (up to 1 MB) so an agent can pick up a file someone else relayed. Text comes back as text, images as images, other files as base64.

relay

relay_attached_file

ChatGPT only: relay a file from the conversation (the host passes it as a file reference) and get a temporary download link.

upload

create_upload_link

Relay a file of any size up to 100 MB. Save the file to local disk first, call this with its path, then run the returned curl command in your shell to upload it. The download link works as soon as the upload finishes. Requires outbound network access to code.easyllms.com; if curl is blocked, ask the user to allow that domain in their sandbox network settings (on claude.ai: Settings > Capabilities > Code execution).

File Relay — questions

Answers built from our own checks of this server.

What can File Relay do?

It exposes 5 tools, read directly from the server on our last check. Among them: create_upload_link, delete_file, get_file_info, read_file, relay_attached_file. 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 →

Is File Relay working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 327 ms. The bar chart above shows every period we have measured.

How do I connect File Relay?

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

Does File Relay need an API key?

No. File Relay completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is File Relay?

It answers our handshake in 327 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
