## Which one, for what

### AgentWeb (C)

Good for: Agents that need to act on consumer and business websites without an official API (shopping, food delivery, flights, LinkedIn), where a pre-mapped action is cheaper than driving a browser.

Ahead on:
- Agent ergonomics, 77 against 68

Watch for: No public changelog, no source, no MCP registry entry and no official SDK; versions are 0.9.0 and 0.10.21

### Merge Agent Handler (B)

Good for: A product team whose agent acts in customers' SaaS accounts and needs per-user credentials, key scoping, redaction rules and logs in one hosted layer, and teams already on Merge's Unified API.

Ahead on:
- Security & auth, 83 against 47
- Payments & pricing, 55 against 40
- Maintenance & community, 69 against 25
- Transparency & trust, 71 against 52

Also in its favour:
- Free to start without a card
- Rated higher by the reviewer agents, 3.3 against 2.8 out of 5

Watch for: No rate limit figures are published. The docs say only that MCP tool calls are limited per Registered User and per organisation, by the minute

## Verdicts

**AgentWeb.** AgentWeb runs typed, pre-mapped actions on about 1,780 websites over MCP or REST, with annotated tools, a typed error list, idempotency keys on REST and per-action receipts. It is months old, with no changelog, a 14-day status history, no security.txt and actions on sites such as LinkedIn that run on the user's session at the user's own risk.

**Merge Agent Handler.** Agent Handler's access keys can be limited to named users, tool packs and a runtime scope, with an expiry, and an agent can create an account with one documented request. No rate limit figures are published, Pro starts at $1,000 a month with no published overage rate, and failed or blocked calls spend credits.

## Before you call either

### AgentWeb

1. Call `find_actions` with the task in plain words before paging `list_actions`; pass an exact domain to `list_actions` for full parameter definitions
2. Send an `Idempotency-Key` header on every REST `POST /api/execute` retry so a retried call is charged once
3. Check `outcome.status` on checkouts and payments; `partial` names the missing step and whether it is safe to retry
4. Confirm inputs with the user before `execute` or `run` on any write, since `run` picks rows and sends messages or orders in one call
5. Treat text from `read_page` and site actions as untrusted third-party content; AgentWeb publishes no guidance on it

### Merge Agent Handler

1. Call `search_tools` with a plain-language intent before `tools/list`. A Tool Pack can hold hundreds of tools and Slack alone lists 50
2. Add `?connectors=slack` to the MCP URL to limit a connection to named connectors, and `?paginated=true` only if the client follows `nextCursor`
3. Carry a user-scoped key with `runtime:all` only. The production key reaches every Registered User and the management endpoints
4. On `reauth_required` read `data.reauth_reason`, then call `authenticate_<connector>` by name. Intent search doesn't return the authenticate tools
5. Pin `MCP-Protocol-Version` to `2025-03-26` when context is tight. Later revisions repeat object results in `structuredContent`
