Why the edge:
- Reliability, Apollo API + MCP +47: Apollo API + MCP 75 (Status page at status.apollo.io, now on Better Stack, with eight components and incident history (20). Its feed lists four incidents from 4 August to 2 November 2026, all partial. Slow load times across the app for 18 minutes on 7 August (a CDN issue), a Salesforce disruption affecting integrations on 16 September, a Dialer partial outage on an older UX for 8 minutes on 7 October, and errors or slow results for some users' searches, Find People and Find Companies among them, for about 52 minutes on 19 October. Maintenance windows aren't counted. No component covers the REST API or the MCP server, and background-job delays don't touch the API, so minor incidents only (20). Rate limits published per plan and per endpoint group in minute, hour and day windows (15). 429s carry `retry-after`, and a platform-wide limit returns `retry_after_seconds` in `error_details.suggestions`. No idempotency or safe-retry guidance for the write endpoints (10 of 15). No SLA found (0). REST and MCP are generally available, no beta label (10).); Databar 28 (Hosted lines. No status page linked from the site or docs (0). No incident history to read (5). The 20 August changelog says rate limits return 429, but no numbers were found in the docs read (5 of 15). The SDK backs off on 429 per the 28 September entry, tasks can be cancelled with a refund, and no Retry-After or idempotency key is documented (8 of 15). No SLA found (0). The MCP server left beta on 15 July 2026 and the API is generally available (10). 0+5+5+8+0+10 = 28.)
- Transparency & trust, Apollo API + MCP +18: Apollo API + MCP 73 (Closed service with published terms naming ZenLeads Inc. d/b/a Apollo.io. The MCP plugin repo is MIT (15). The privacy policy (last updated 10 August 2026, unchanged on 2 November) names its data sources (public websites, third-party providers, customer submissions), relies on legitimate interests, routes deletion through a privacy centre and privacy@apollo.io, and links a DPA. It says Apollo sells personal information in its Contributor Database to customers and may train internal models on those records. Retention is 'consistent with the purposes', with no periods (22 of 30). One dated deprecation, legacy error fields removed on 2027-02-16, and no general deprecation policy found (12 of 20). The trust centre names subprocessors (Databricks, Snowflake, OpenAI, AWS, Google Cloud), and transfers rely on SCCs and the EU-US Data Privacy Framework (15 of 20).); Databar 55 (Closed service with terms effective 1 October 2026 naming Databar, Inc. of Delaware (15 of 30). The privacy policy keeps data 'for as long as needed' with no periods; the docs give 24 hours for task results; a DPA is part of the agreement but was not read (15 of 30). The changelog flagged breaking API and SDK changes on 20 August 2026, and the terms let Databar retire any form of programmatic access; no notice period stated (8 of 20). Sub-processors are disclosed under the DPA, which was not read; data is processed in the United States (5 of 20). 15+15+8+5 = 43.)
- Maintenance & community, Databar +15: Apollo API + MCP 58 (Newest dated release is Apollo CLI v2.2.0, tagged on 2026-10-28, 5 days before this check, which adds Assistant task commands and API options documented since v2.0.0 (30). The API changelog's only entry, structured API errors, is dated 2026-09-18. In the last 90 days that entry and the CLI tag (counted half) make 1.5 dated changes, short of three. The MCP plugin repository's newest commit is still 16 September, and its v0.1.1 tag and the registry entries are unchanged since July (0). Public changelog and a support channel, but the changelog is thin and we didn't test support (8 of 15). Listed in the official MCP registry as io.github.apolloio/apollo-mcp, a GitHub-verified namespace, version 0.1.1 published 2026-07-20 (15). No SDK packages to judge. The plugin repository has a registry publish workflow (5 of 10).); Databar 73 (Closed service. Python SDK 2.9.0 on 30 October 2026, 7 days before this check (30). SDK 2.7.0 and 2.8.0 on 6 October and changelog entries on 23, 24, 27, 28, 29 and 30 September and 1 October (20). A public changelog, roadmap and feedback portal, an email address, and a Slack channel on Scale (10 of 15). An official Python SDK and CLI, no other languages (10 of 15). Package health not checked (3 of 10). 30+20+10+10+3 = 73.)
- Security & auth, Apollo API + MCP +13: Apollo API + MCP 60 (Keys sent in the `x-api-key` header. Scoped keys are the default and are limited to chosen endpoints (403 elsewhere), and keys can be regenerated or deleted. OAuth for the MCP in chat clients. Headless MCP use needs a master key that reaches every endpoint (25 of 30). Scoped keys give least privilege on REST. The MCP has 13 write actions, including sending one-off emails, adding contacts to sequences and buying domains and mailboxes, with no read-only mode, and approval is left to the client (10 of 20). Results include third-party-sourced profile text, emails and call transcripts, and we found no prompt-injection guidance (3 of 15). Usage stats endpoint, rate-limit usage headers, and audit logging listed in the trust centre (8 of 15). ISO 27001 and SOC 2 Type 2 per the SafeBase trust centre, disclosure by email to security@apollo.io, no bug bounty found, no security.txt (14 of 20).); Databar 47 (A workspace API key in a header, never in the URL, and OAuth on the MCP with a Connected apps page to revoke access. No scopes found (20 of 30). No read-only key; MCP balance checks and confirmation above 50 credits, a 30-day trash for workbooks and tables, but row, column and table deletes through the tools (12 of 20). Enrichment results include web-scraped and AI researcher text, with no prompt-injection guidance (3 of 15). Credit usage charts, transaction logs and per-request data logs (12 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). 20+12+3+12+0 = 47.)
- Payments & pricing, Databar +5: Apollo API + MCP 30 (No x402, MPP or L402 (0). Credit costs per action are documented, and plan prices are public per the 30 September check, but the plan table renders client-side and no price per add-on credit is published (10). Free plan with API rate limits listed in the docs. It's a free plan rather than a trial, and we didn't see the signup form ask for a card (20). A person signs up in a browser with a work email (0).); Databar 35 (No x402, MPP or L402 (0). Plan prices and credits are public, and each connector's credit cost is shown before a run and in the enrichment's pricing field; credits aren't sold per call outside a plan (15 of 20). A 14-day premium trial with no card, per the pricing FAQ (20). A person signs up in a browser, and API access needs a paid plan (0). 0+15+20+0 = 35.)
