A person signs up in a browser (0). 0+20+15+0 = 35.\n\n### Maintenance \u0026 community: LeadMagic API + MCP +10\n\n- LeadMagic API + MCP (80): The hosted MCP server is in the official MCP registry as io.leadmagic/server (and io.leadmagic/sheets) since 3 October 2026, with 2.23.5 published on 15 October 2026, 20 days before 4 November (30). The changelog's newest entry is api 3.3.1 on 17 September, which alone would give 20. In the 90 days from 6 August, changelog entries on 25 August (web 3.2.0 and api 3.3.0) and 17 September (api 3.3.1), and ten io.leadmagic/server versions between 3 and 15 October (20). Public changelog and support, issue handling not visible (10 of 15). In the official MCP registry under the verified io.leadmagic namespace (15). No packages to judge (5 of 10). 30 + 20 + 10 + 15 + 5 = 80. The MCP section of the changelog stops at mcp 2.5.0 (2 May 2026), while the server card reports 2.23.6, undated.\n- ZeroBounce (70): Closed service. The JavaScript SDK 3.0.0 was published on 25 October 2026 (30). No API changelog; the dated changes found in 90 days are that release and status-page notices, fewer than three releases (10 of 20). Support by email and 24/7 chat per the docs, a public status page; replies not tested (10 of 15). Official SDKs in many languages and an MCP server (15). Package health not checked (5 of 10). 30+10+10+15+5 = 70.\n\n## Score by category\n\n| Category | Weight | LeadMagic API + MCP | ZeroBounce | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 52 | 75 | ZeroBounce +23 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 93 | 54 | LeadMagic API + MCP +39 |\n| Agent ergonomics | 13% (16.2 this run) | 71 | 69 | LeadMagic API + MCP +2 |\n| Security \u0026 auth | 14% (17.5 this run) | 63 | 65 | ZeroBounce +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 35 | ZeroBounce +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 80 | 70 | LeadMagic API + MCP +10 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 65 | 63 | LeadMagic API + MCP +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **63.3 · B** | **62.4 · B** | |\n\n## Facts side by side\n\n| Fact | LeadMagic API + MCP | ZeroBounce |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | LeadMagic | Hertza L.L.C.

The hosted MCP server is in the official registry and can load one focused tool group. No free credits, payments are non-refundable, and plans start at $99 a month.\n\n**ZeroBounce.** ZeroBounce's v2 API verifies emails with detailed status and sub-status codes, publishes per-endpoint limits, a Statuspage with short incidents only in the last 90 days, SOC 2 Type 2 and ISO 27001, and $0.0195 per email at the smallest pack. The documented key travels in the query string, and there is no OpenAPI contract.\n\n## Before you call either\n\n### LeadMagic API + MCP\n\n1. Connect only the focused MCP group the task needs, such as https://mcp.leadmagic.io/mcp/enrichment-core for lookups\n2. Call `preview_cost` before bulk work. It's free\n3. Read `X-Credits-Remaining` after each call instead of polling the balance\n4. Treat 402 as out of credits and wait out Retry-After on 429\n5. Follow each table tool's returned approval step before deletions, cell edits or runs over 5 credits\n\n### ZeroBounce\n\n1. Use the regional host (api-us or api-eu) that matches the data, and test with the sandbox addresses, which spend no credits\n2. Set `timeout` (3 to 60 seconds); slow mail servers return unknown, which is free to retry later\n3. Stay under 80,000 validations per 10 seconds and avoid repeated bad requests, which block the key for an hour\n4. Use the bulk file API for large lists instead of looping on /v2/validate\n5. Keep the key out of logs; the API takes it only as `api_key` in the URL\n\n## Questions\n\n### Which is better for AI agents, LeadMagic API + MCP or ZeroBounce?\n\nLeadMagic API + MCP and ZeroBounce score within a point of each other on agent readiness, 63.3 (B) and 62.4 (B).
