Verdicts
Monid
An agent can search a catalogue of paid data and media endpoints by need, read each one's schema and price, and pay per run from one prepaid balance with person-set budgets, or by x402. Rate limits have no numbers, paid runs take no idempotency key, no security contact was found, and the skill sends a known email to setup telemetry.
One
One's remote MCP server has three tools, OAuth 2.1 sign-in with PKCE and a consent screen that sets read only, read and write, full or per-action access for each connection. A person must sign in through a browser, the SOC 2 audit is unfinished, and the site's changelog stops at 13 July 2026.
Before you call either
Monid
- Call inspect before every run and pass body, queryParams and pathParams in the shape it returns; run inputs aren't typed at the API level.
- Treat a
COMPLETEDrun as success only whenproviderResponse.httpStatusis 2xx; provider errors complete with a non-2xx status and aren't charged. - Don't resend a paid run after a timeout without checking
GET /v1/runs; there's no idempotency key and a repeat bills again. - Start with small
maxItemson per-result endpoints; limits often apply per query, not per call. - Pass
--clientalone tomonid setup, or skip it; the email flag only feeds Monid's setup telemetry.
One
- Call
list_one_integrationsfirst and read each connection'saccessfield. When the policy isactions, run those ids directly without callingfind_one_actions - Send every operation a task needs in one
find_one_actionscall, up to 10requests, each a platform and a short intent with no IDs, names or message text - When a document comes back as a digest, call
find_one_actionsagain withloadand asectionname. Don't guess parameters the digest left out - After a timeout on
execute_one_action, check whether the write took effect before sending it again. No idempotency key is documented - A 403 for a call outside the grant won't succeed on retry. Ask the user to widen the grant in the dashboard or reconnect

Disclosure
Monid competes with letme, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
