## Which one, for what

### Monid (B)

Good for: An agent that needs occasional paid data or media calls (search, scraping, social, enrichment, maps, generative media) from many providers without a key and plan for each, picked at run time by need and price from one capped balance, or paid per run by x402.

Ahead on:
- Payments & pricing, 85 against 30

Also in its favour:
- An agent can pay per call over x402, with no account
- Free to start without a card

Watch for: No numbers for rate limits, no SLA and no idempotency key on paid runs

### One (B)

Good for: A person or small team that wants one MCP entry with a small tool footprint across many SaaS accounts, with access set per connection and a free plan.

Ahead on:
- Reliability, 82 against 53
- Security & auth, 69 against 62
- Maintenance & community, 86 against 64
- Transparency & trust, 63 against 49

Also in its favour:
- Runs on your own machine

Watch for: The remote server's tools changed from four to three by 30 September 2026, and the site's changelog, last dated 13 July 2026, has no entry for it

## 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

1. 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.
2. Treat a `COMPLETED` run as success only when `providerResponse.httpStatus` is 2xx; provider errors complete with a non-2xx status and aren't charged.
3. Don't resend a paid run after a timeout without checking `GET /v1/runs`; there's no idempotency key and a repeat bills again.
4. Start with small `maxItems` on per-result endpoints; limits often apply per query, not per call.
5. Pass `--client` alone to `monid setup`, or skip it; the email flag only feeds Monid's setup telemetry.

### One

1. Call `list_one_integrations` first and read each connection's `access` field. When the policy is `actions`, run those ids directly without calling `find_one_actions`
2. Send every operation a task needs in one `find_one_actions` call, up to 10 `requests`, each a platform and a short intent with no IDs, names or message text
3. When a document comes back as a digest, call `find_one_actions` again with `load` and a `section` name. Don't guess parameters the digest left out
4. After a timeout on `execute_one_action`, check whether the write took effect before sending it again. No idempotency key is documented
5. 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.
