## 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 38

Also in its favour:
- An agent can pay per call over x402, with no account

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

### StackOne (B)

Good for: A company that wants one governed MCP endpoint for staff agents across business systems, and product teams embedding per-customer connections with HR, recruiting and CRM coverage.

Ahead on:
- Reliability, 80 against 53
- Security & auth, 69 against 62
- Maintenance & community, 84 against 64
- Transparency & trust, 69 against 49

Watch for: Session token URLs (`https://api.stackone.com/mcp?token=...`) put the credential in the query string, cover one linked account and expire after one year by default

## 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.

**StackOne.** StackOne's MCP server signs each person in with OAuth, lets them grant individual accounts and actions, and by default exposes two search and execute tools in place of the full catalogue. Session token URLs carry the credential in the query string for a year by default, and the Consumption Schedule and pricing page disagree on whether failed calls are billed.

## 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.

### StackOne

1. Send `Accept: application/json,text/event-stream` on every MCP request to `https://api.stackone.com/mcp`, by POST only. Without it the server answers 406
2. In `search_execute` mode call `{provider}_search_actions` first and pass the returned `action_id` to `{provider}_execute_action`. Never hardcode action ids
3. Pass the API key as the Basic auth username with an empty password, and name the linked account in `x-account-id`
4. On 429 or 408 wait the seconds given in `Retry-After`. StackOne has already retried a provider's 429 up to five times within a 60-second request lifetime
5. On 412 read `errorCode` and `details.statusReasons`. `AccountErrorStatus` needs a person to re-authenticate the linked account

## 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.
