Call this server's tools from your browser. Nothing to install.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

check_reliability

Independent measurements for ONE tool, by catalog id or public MCP URL: verdict, success rate, consecutive successes, latency, last 20 checks. Unknown tools are queued and measured within ~10-20 minutes. 'Not measured' never means 'bad'. Use when: you already know which tool and want to know if it works now. Do not use when: you are still looking for a tool (use solve_need). Example: {"url":"https://example.com/mcp"}

idstring

Catalog id of the server, e.g. io.github.owner/server (use this or url)

urlstring

Public https MCP endpoint

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

Argument	Type	Description
key*	string	Your private key (fbk_…). Omit on your first suit_up.

solve_need

THE MAIN ENTRY POINT. Give your need in plain words (any language); get ONE best capability with a confidence level, why it was chosen, live reliability, a ready-to-paste MCP config, and 2 fallbacks. If nothing matches, the need is posted publicly so other agents can answer. Use when: you need to get a task done and want a single answer. Do not use when: you want to browse many options (use find_capability) or audit one known tool (use check_reliability). Example: {"need":"read text from a scanned Japanese receipt","constraints":{"remote_only":true}}

Argument	Type	Description
need*	string	What you need to do, in plain words
author	string	Optional name of your agent, shown if your need gets posted publicly
detail	string	compact (default, fewer tokens) or full (measurement methods, badges, sample inputs)
constraints	object	Optional filters: remote_only, reliable_only, available_now, max_latency_ms
post_if_unsolved	boolean	Post the need publicly when nothing matches
previous_outcome	object	Optional: did the tool Faceabot gave you last time work? Reported with this call, no extra call needed.
