The server-side track reference last changed on 3 June 2026 and has no changelog, so we scored this line between the two (20 of 30). heap.js 5.3.15, 5.3.16 and 5.3.17 and Android Core 0.9.5 fall inside 90 days (20). Dated public changelogs and a community at community.contentsquare.com, whose response times we didn't check (8). Client SDKs for web, Android, iOS, React Native and Flutter are current. The Node server client is from 2016 (10). CI not checked (5). Total 63. Per the 7 October check, not re-read on 4 November (developers.heap.io is paused on its terms). The three heap.js releases still fall inside the 90 days from 6 August.\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### Security \u0026 auth: RudderStack MCP +21\n\n- Heap (41): Track, identify and property calls carry no secret. The OpenAPI fragment declares an empty security requirement and the only identifier is the environment ID that the web snippet publishes. User deletion uses one admin-generated API key per account, exchanged for a temporary token. No scopes or rotation guidance found (8 of 30). Ingest is write-only by design. Deletion of up to 10,000 users has no confirmation step (5). The API returns no untrusted content (10). Audit logs are unchecked because help.heap.io answered with a bot check, so none are counted (0). Contentsquare publishes a signed security.txt valid to 31 January 2028 on contentsquare.com (not on heap.io), a disclosure policy, an invitation-only YesWeHack bounty, SOC 2 Type II and ISO 27001 (18). Total 41. Per the 7 October check, not re-read on 4 November, because heap.io and contentsquare.com terms bar robots and crawling.\n- RudderStack MCP (62): OAuth with PKCE and dynamic registration, scopes not published (22 of 30). Access classes, a read-only surface and confirmation advice for writes (16 of 20). Selected sensitive fields in event payloads and errors are redacted or hashed before they reach the model, but event payloads are still untrusted text (8 of 15). No audit log of MCP calls found (0). SOC 2 Type 2, HIPAA with a BAA, and a SECURITY.md with a private reporting address; no security.txt (404) (16 of 20). 22 + 16 + 8 + 0 + 16 = 62.\n\n### Transparency \u0026 trust: Heap +15\n\n- Heap (66): Closed service with published terms, now Contentsquare's master services agreement (15). The DPA (June 2026) caps Product Analytics retention at 37 months from collection unless agreed otherwise and links the sub-processor list. heap.io still carries a 2019 website terms page from Heap Inc. beside the Contentsquare documents (22). No deprecation policy for the API was found. Contentsquare's docs carry migration guides from the Heap SDKs to the CSQ SDK without an end date that we found (4). Sub-processor list (June 2026) with locations, AWS in Ireland, Frankfurt and Virginia and OpenAI for Sense Chat (20). Total 61. Per the 7 October check, not re-read on 4 November, apart from the heap.io website terms (still dated 30 August 2019) and Contentsquare's terms of service (29 January 2026).\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### Schema \u0026 documentation: RudderStack MCP +9\n\n- Heap (57): OpenAPI 3.1 fragments are embedded in the Markdown of the track and identify pages. No single spec file was found, the property pages we read had empty fragments and user deletion is prose only (15). llms.txt and a .md copy of every page (10). Descriptions state purpose, limits and reserved keys, with little on when not to use a call (12). Required fields are marked and lengths stated in prose, with string types throughout, no enums and a free-form `properties` object (8). Curl examples on every page. Track and identify document 200 and 400 with an empty object, and only user deletion describes its error body (7). SDK changelogs are dated, but no changelog or version policy for the server-side API was found. Paths mix unversioned, v1 and v0 (5). Total 57. Per the 7 October check, not re-read on 4 November, because developers.heap.io sits on a host whose terms bar robots.\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### Payments \u0026 pricing: RudderStack MCP +5\n\n- Heap (25): No x402, MPP or L402 (0). The Free plan and its 10,000-session limit are public. Growth needs an estimate after signup and Pro and Premier say Contact Us, so no paid price is published (5). Free plan with APIs included. No card is mentioned on the pricing page, and the signup form needs JavaScript we couldn't run (20). A person signs up in a browser and copies the environment ID (0). Total 25. Per the 7 October check, not re-read on 4 November (www.heap.io is paused on its terms).\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).

Limits are published, bulk calls take 1,000 items and track accepts an idempotency key. The API returns no analytics, and ingest calls carry no secret beyond the environment ID. Heap's help centre lists a Heap MCP article, which a bot check stopped us reading, so the MCP server is ungraded.\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### Heap\n\n1. Send EU projects to https://c.eu.heap-api.com instead of https://heapanalytics.com. The path stays the same\n2. Pass one of `identity` or `user_id` on track, never both\n3. Set `idempotency_key` on every track event so a retry doesn't duplicate it\n4. Stay under 30 requests per 30 seconds per identity, or batch up to 1,000 events in one bulk call\n5. For deletion, exchange the app_id and API key of the Main Production environment for a token first. Any other environment ID returns Unauthorized\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, Heap or RudderStack MCP?\n\nRudderStack MCP scores 54.7 (C) on agent readiness against Heap's 48.2 (D), and leads in 5 of 7 scored categories. Heap leads on transparency \u0026 trust.\n\n### Do Heap and RudderStack MCP need an API key?\n\nHeap takes an API key or an OAuth sign-in. RudderStack MCP uses an OAuth sign-in.\n\n### Can an agent call Heap and RudderStack MCP without installing anything?\n\nYes. Heap has a hosted endpoint at https://heapanalytics.com and RudderStack MCP at https://mcp.rudderstack.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/heap-vs-rudderstack-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/heap-vs-rudderstack-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"heap\", \"b\": \"rudderstack-mcp\"}`.
