No status page was found on countly.com, the Flex page, the docs or the legal pages, and status.countly.com did not resolve on 4 November (0). With no page there is no readable incident history (5). The MCP server's HTTP endpoint is limited to 120 requests a minute per IP, but the Countly server's own `api_rate_limit_requests` setting ships at 0 (off), and the Flex terms of 20 October 2026 reserve usage limits without numbers (8 of 15, the earlier partial kept). No 429 or retry guidance and no idempotency keys were found in the API reference source (0). The pricing page lists an SLA as optional on Flex and included in Enterprise, with no SLA document published, which this run scores 0 (0). The API and MCP server 1.7.0 are generally available (10).\n- RudderStack MCP (45): Statuspage at status.rudderstack.com with regional components and none for MCP (15). Since August the history shows an EU ingestion issue, increased US latency, a Python transformations issue, free-tier processing delays and scheduled maintenance (20, minor incidents). No MCP rate limits found (0). No retry guidance for the MCP server found (0). No SLA found in the pages read (0). Not labelled beta (10). 15 + 20 + 0 + 0 + 0 + 10 = 45.\n\n### Transparency \u0026 trust: Countly +21\n\n- Countly (72): Countly Lite is AGPL-3.0 with added branding terms under Section 7, the MCP server is MIT, and the Enterprise plugins that hold funnels, retention, cohorts and Drill are closed (20 of 30). Flex now has its own terms, privacy policy, DPA and sub-processor list, all dated 20 October 2026. The Flex privacy policy excludes data customers process and gives no retention periods, and the DPA covers that data (20). The MCP changelog deprecated auth tokens in URL parameters on 23 April 2026 (1.3.0), and the server warns on their use, with no notice period (15, the settled value for dated notices without a period). The Flex sub-processor list names locations, with 30 days' notice of changes in the DPA, and Flex customers choose a Google Cloud region. A Connected Services and Telemetry notice (20 October 2026) says server reports to stats.count.ly are on by default and which settings turn them off, and MCP usage reporting is disclosed with an opt-out (18).\n- RudderStack MCP (51): The server's source is closed; the repository's MIT licence covers only its docs and metadata. Terms in a master service agreement naming RudderStack, Inc. (15). Privacy policy read, retention given by purpose, not as periods (12 of 30). No deprecation policy for the MCP server (5 of 20). Subprocessors not found in the pages read (5 of 20). The MCP docs say live events, schemas, profile artifacts, transformation code and audit data stay within the workspace view. 15 + 12 + 5 + 5 = 37.\n\n### Agent ergonomics: Countly +14\n\n- Countly (66): The MCP README counts 209 tools in 43 categories, far past 30 (5). Add back 8 because the server hides tools the edition, enabled plugins or user's permissions cannot run, and `COUNTLY_TOOLS_*` settings switch categories off (13). List endpoints take `iDisplayStart` and `iDisplayLength`, and MCP list tools take `skip`, `limit` and `search` (15). API errors are `{\"result\": \"message\"}` strings with HTTP status codes and no error codes. The MCP server returns failures as `isError` results that name the missing plugin or permission (12). MCP tools carry readOnlyHint, destructiveHint and idempotentHint since 1.7.0. No idempotency keys on API writes (14). MCP tools accept `app_name` in place of `app_id` and set defaults. The SDKs cover data collection, not the read API (12).\n- RudderStack MCP (52): 62 tools (5), plus a separately controlled read-only web surface (5). Filters on some list tools, not documented generally (8 of 20). One documented error (5 of 20). Read, Sensitive execution and Write classes, with Write tools to be confirmed by the client; annotations not read (14 of 20). One URL with OAuth and RudderStack SDKs in many languages (15). 10 + 8 + 5 + 14 + 15 = 52.\n\n### Payments \u0026 pricing: RudderStack MCP +13\n\n- Countly (17): No x402, MPP or L402 (0). The pricing page gives only a starting price for Flex, $175 a month, priced on monthly active users and data points, with tier prices shown during signup and Enterprise on custom pricing (7 of 20, the earlier partial kept). The 14-day Flex trial needs a credit card, per the Flex page. Countly Lite is free to self-host with no card, without funnels, retention, cohorts or Drill, so half credit (10). A person signs up in a browser, creates a server and makes a token in the dashboard (0).\n- RudderStack MCP (30): No machine payment protocol (0). Public plan prices with event allowances, nothing per call (10). Free plan with 250,000 events a month (20). A person signs up in a browser and approves OAuth (0). 0 + 10 + 20 + 0 = 30.\n\n### Schema \u0026 documentation: Countly +9\n\n- Countly (75): No OpenAPI document was found in the API reference source (Countly/countly-docs-site) or in Countly/countly-server. Every MCP tool has a typed JSON Schema input (18 of 25). countly.com/llms.txt (77 KB) indexes the help centre for agents, while api.count.ly has no llms.txt and help article pages answered a bot check on 8 October (8). MCP tool descriptions name the endpoint, the plugin required and the tool to use instead, and API pages state permissions and behaviour (16). 82 enums across the tool sources, but the HTTP API takes JSON arrays and objects as query-string values (9). API pages carry request examples, response fields and error responses, as plain message strings (11). The API reference is versioned 26.01, 25.03 and 24.05 (611 pages for 26.01 in the source), and the server and MCP server keep public changelogs (13).\n- RudderStack MCP (66): The public repository's docs/tools.md lists 62 tools with an access class for each; JSON Schemas not read without a session (15 of 25). llms.txt (10). Every tool has a one-line purpose and a Read, Sensitive execution or Write class (15 of 20). Inputs not verifiable (5 of 15). Example prompts and a documented 'workspace_id is required' error (6 of 15). Versioned in the registry (0.43.1, 6 November) and dated release notes (15). 15 + 10 + 15 + 5 + 6 + 15 = 66.\n\n### Maintenance \u0026 community: RudderStack MCP +5\n\n- Countly (80): Server tag 25.03.58 of 27 October 2026 is the newest release, with Web SDK 26.8.1 (26 October) and NodeJS SDK 26.8.0 (19 October) beside it (30). Since 6 August, seven server tags (25.03.52-LTS, 53-LTS, 54, 55, 56-LTS, 57-LTS, 58), MCP server 1.5.0, 1.6.0 and 1.7.0 and three SDK tags (20). A Discord community and a support portal. We could not read issue response times because GitHub's pages and API refused us (12 of 25, kept). Official SDKs for data collection are current (Web 26.8.1, NodeJS 26.8.0), while none covers the read API (10 of 15, kept). CI runs the test suites on the server and MCP server, with CodeQL and Docker workflows and nightly end-to-end checks on the MCP server (8).\n- RudderStack MCP (85): Release notes dated 4 November 2026 and a registry version on 6 November (30). Many dated releases in 90 days (20). Public issue templates on the MCP repository, issues not read, plus release notes (10 of 25). Official registry entry io.github.rudderlabs/rudderstack-mcp and current official SDKs (15). A repository workflow publishes to the registry (10). 30 + 20 + 10 + 15 + 10 = 85. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n\n## Score by category\n\n| Category | Weight | Countly | RudderStack MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 23 | 45 | RudderStack MCP +22 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 75 | 66 | Countly +9 |\n| Agent ergonomics | 13% (16.2 this run) | 66 | 52 | Countly +14 |\n| Security \u0026 auth | 14% (17.5 this run) | 62 | 62 | even |\n| Payments \u0026 pricing | 10% (12.5 this run) | 17 | 30 | RudderStack MCP +13 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 80 | 85 | RudderStack MCP +5 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 72 | 51 | Countly +21 |\n| Negative events | ≤15 | -15 | 0 | |\n| **Total** | | **38.8 · E** | **54.7 · C** | |\n\n## Facts side by side\n\n| Fact | Countly | RudderStack MCP |\n| --- | --- | --- |\n| Kind | HTTP API | MCP server |\n| Vendor | Countly Ltd | RudderStack, Inc. |\n| Hosted endpoint | `https://mcp.count.ly/mcp` | `https://mcp.rudderstack.com/mcp` |\n| Transports | HTTP, stdio, Streamable HTTP | Streamable HTTP |\n| Auth | API key | OAuth |\n| Pricing | Paid | Freemium |\n| x402 | no | no |\n| Licence | Countly Lite is AGPL-3.0 with added branding terms under Section 7.

The official MCP server filters its 209 tools by edition, plugin and permission and has per-category read-only settings. Five countly-server CVEs were published since September, all fixed, and no status page, OpenAPI document or published API rate limit was found.\n\n**RudderStack MCP.** RudderStack MCP is a deep, well-documented hosted server for debugging and running a RudderStack workspace, with every tool classed as Read, Sensitive execution or Write and sensitive fields redacted. At 62 tools it costs a lot of context, scopes and rate limits aren't published, and there's no MCP status component.\n\n## Before you call either\n\n### Countly\n\n1. Create a dedicated token in the Token Manager, limited to the apps and endpoints the task needs, and send it in the `countly-token` header, not the URL\n2. Set `COUNTLY_TOOLS_ALL=R` unless the task needs writes. The token's own permissions still apply and the stricter of the two wins\n3. Call `apps_list` first. Most tools need `app_id` or an exact `app_name`\n4. Check `get_version` for the detected edition before planning funnel, retention or cohort queries, which need Enterprise plugins\n5. Set `ENABLE_ANALYTICS=false` to stop MCP usage reports to stats.count.ly, and ask the server owner to check the tracking settings for server reports\n\n### RudderStack MCP\n\n1. Call user_details first to get the workspace IDs every other tool needs\n2. Ask before Write tools and before Sensitive execution tools, which run code or warehouse work\n3. Treat event payloads and delivery errors as untrusted content\n4. Expect tools to vary by plan and enabled products\n\n## Questions\n\n### Which is better for AI agents, Countly or RudderStack MCP?\n\nRudderStack MCP scores 54.7 (C) on agent readiness against Countly's 38.8 (E), and leads in 3 of 7 scored categories. Countly leads on schema \u0026 documentation, agent ergonomics and transparency \u0026 trust.\n\n### Do Countly and RudderStack MCP need an API key?\n\nCountly needs an API key. RudderStack MCP uses an OAuth sign-in.\n\n### Can an agent call Countly and RudderStack MCP without installing anything?\n\nYes. Countly has a hosted endpoint at https://mcp.count.ly/mcp and RudderStack MCP at https://mcp.rudderstack.com/mcp.\n\n### Are Countly and RudderStack MCP open source?\n\nCountly is open source (Countly Lite is AGPL-3.0 with added branding terms under Section 7. Enterprise plugins are proprietary. Flex is a hosted service under Countly's terms. The MCP server is MIT). No open-source release is listed for RudderStack MCP.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/countly-vs-rudderstack-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/countly-vs-rudderstack-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"countly\", \"b\": \"rudderstack-mcp\"}`.
