# Fix list: MoEngage From Anchor Terminal's listing at https://www.anchorterminal.com/tools/moengage, the October 2026 research run, assessed 9 October 2026. Grade B, 65.2 out of 100. This is everything the published grade says the listing lacks, the biggest possible gain to the total first. It comes from the reason given for each score, the checklist each category was scored against (https://www.anchorterminal.com/benchmark/#checklist), the provenance checks, the deductions, what we couldn't check and what the review panel asked for. A fix counts at the next check, once it's public. For a coding agent working on MoEngage: work through the items below in the product, its docs and its public pages. Each category gives the reason for its score, with the points each checklist item earned, and the checklist itself, so the gap is the items that earned less than their points. Change the product, not the wording, and keep a note of what you changed and where it's published. ## 1. Payments & pricing, 0 out of 100, up to 12.5 more on the total Why it scored 0: No x402, MPP or L402 (0). No prices are published. The pricing page lists Growth and Enterprise plans with a sales contact (0). No free tier or trial was found (0). A person has to buy through sales and create keys in the dashboard (0). Total 0. The checklist (https://www.anchorterminal.com/benchmark/#checklist-payments): The published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/). - 40, a machine payment protocol (x402, MPP or L402) on the tool's own endpoints. 10 to 30 when it covers only some endpoints or only goes through a third party, and the note says which. - 20, per-call or per-unit pricing published without a login. 10 for public plan-only pricing, 0 for "contact sales" or prices behind a login. - 20, a free tier or trial that doesn't need a card. - 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API). Payment platforms and agent wallets rarely charge for their own API over a machine protocol, so the first line has steps for them, and the highest one that applies counts. 40 when x402, MPP or L402 runs on all their own endpoints, 30 when it runs on part of their own API, 25 when their merchants can accept one, 20 for running a facilitator, 15 for paying as a buyer, and 0 when the only protocol is their own. Merchant acceptance sits above a facilitator because the platform's own customers can charge agents through it, while a facilitator settles for sellers who wire up the protocol themselves. The counter-argument (a facilitator does more for the protocol as a whole) has a point. Each note says which step applied. Open-source software you run yourself is scored on its hosted or paid option if it has one. A free, self-hosted package with nothing to buy gets 20, 20 and 20 for the last three lines, and 0 to 40 for the first only if it ships a payment protocol. ## 2. Security & auth, 69 out of 100, up to 5.4 more on the total Why it scored 69: Keys can be scoped to chosen API groups and individual APIs, regenerated and archived, and can use OAuth 2.0 client credentials with tokens of 5 to 60 minutes or AWS STS role ARNs. This dashboard is in early access, and Segmentation and Inform accept Basic authentication only (26). One endpoint, `GET /installInfo`, takes an attribution key in the query string, so 3 of the 10 points for that line come off (23). Keys limited to selected APIs, an API firewall that restricts categories by IP address, an MCP server bound to the user's role that builds drafts and can't publish, and a campaign approval workflow sold as an add-on. The legacy campaigns API can still publish (16). The MCP server masks PII attributes, email and mobile number, and the AI policy describes schema validation and allowlisted tool calls for MoEngage's own agents. No guidance for outside agents reading customer content was found (7). Audit logs are listed as a plan item on the pricing page. Whether they record API calls wasn't established (7). Responsible disclosure policy with safe harbour, a 24-hour acknowledgement and a PGP key, no bug bounty, no security.txt, and SOC 2 Type 2, ISO 27001, ISO 27701, ISO 22301, CSA STAR Level 1 and HIPAA on the security page (16). Total 69. The checklist (https://www.anchorterminal.com/benchmark/#checklist-security): - 0 to 30, the credential model. 30 for OAuth 2.1 with scopes, or scoped and revocable keys with rotation. 20 for plain revocable API keys. 10 for one all-powerful key. 10 off when a secret can travel in a URL query string as a documented option. - 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions. - 0 to 15, prompt-injection posture where the tool returns untrusted content (documented mitigations or guidance). A tool that returns no untrusted content gets 10. - 0 to 15, audit logs or per-call visibility for the operator. - 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public. Models are read for retention, whether API data trains models (and whether that's off by default), zero-retention options and certifications. Frameworks for telemetry defaults, approval hooks, guardrails and sandboxing. ## 3. Reliability, 74 out of 100, up to 5.2 more on the total Why it scored 74: Graded on the REST API, with the hosted lines. Statuspage site at status.moengage.com with components for each data centre, among them Data APIs, Push APIs, Custom Segment API and Inform (20). Four incidents between 11 July and 9 October 2026. On 17 August the Inform API in DC-03 returned HTTP 200 for about 16 hours while a subset of messages was never sent, and MoEngage could not replay them. On 27 July DC-01 ran degraded across several services for about four and a half hours after a cloud provider fault, on 25 July Inform and triggered campaigns in DC-01 were degraded for about three hours, and on 24 September the campaign list page showed errors for about 45 minutes. One major incident and two long degradations (8). Numeric limits are published for every endpoint group (15). 429 responses carry `x-ratelimit` headers, the OAuth and some V5 endpoints add `Retry-After`, and V5 campaigns and flow status changes take an `Idempotency-Key`. The Data APIs have no idempotency key (12). The published SLA commits to 99.9 per cent monthly availability with service credits (10). The REST API is generally available, with the Flows endpoints and the API key dashboard in early access (9). Total 74. The checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability): Hosted APIs, MCP servers, models and platforms. - 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own). - 0 to 30, the incident record for the last 90 days on that page. 30 for a clean record or trivial incidents only, 20 for minor incidents only, 10 for one major outage (an hour or more of a core API down, or errors across the board), 0 for several. 5 when there's no history we could read, and the note says so. - 15, rate limits documented with numbers. - 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved. - 10, an SLA published for any paid tier. - 10, the surface agents use is generally available, not beta or preview. Local packages, SDKs, frameworks and stdio MCP servers. - 20, installs from an official package with supported runtimes stated. - 25, a public CI and test suite, passing on the default branch. - 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered). - 15, semver discipline and breaking changes called out in a changelog. - 15, version 1.0 or later, or declared stable. Protocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors. ## 4. Agent ergonomics, 68 out of 100, up to 5.2 more on the total Why it scored 68: List and search calls take `page`, `limit` or a cursor, and the MCP server hides tools the user's role can't use, though it documents 52 tools (15). V5 list calls return `next_cursor`, and campaign, segment, flow and template search calls take filters (17). Errors use a standard envelope with `message`, `type` and `request_id`, V5 adds `code`, `target` and `details`, and authentication failures carry a `MOENGAGE-AUTH-ERROR-CODE` header. Segment creation returns a 400 that names no field (16). `Idempotency-Key` is required on V5 campaign writes and accepted on flow status changes, and Inform deduplicates on `transaction_id` for 5 minutes. The Data and segment APIs have none, and MCP tool annotations couldn't be read without signing in (12). A campaign draft needs three fields. SDKs cover Android, iOS, web and six cross-platform frameworks, but no server-side API client was found (8). Total 68. The checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics): - 0 to 25, context cost. For MCP, the number and size of the tool definitions (25 for ten or fewer compact tools, 15 for 11 to 30, 5 for more than 30, plus up to 10 back for toolsets, dynamic loading or read-only subsets). For APIs, whether responses can be sized (field selection, limits, summaries). - 20, pagination, filtering and output-size controls. - 20, actionable, documented error responses, codes and messages an agent can recover from. - 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations. - 15, sensible defaults, few required parameters, and official SDKs in at least two languages. Models are read for tool use, structured output, prompt caching, context length, batch and SDKs. Frameworks for how much code and how many defaults a tool-calling agent with MCP needs. ## 5. Maintenance & community, 75 out of 100, up to 2.2 more on the total Why it scored 75: The Android SDK changelog has an entry dated 9 October 2026 and the Web SDK one dated 8 October (30). The Web SDK alone has seven dated releases since 11 July, and product release notes are published monthly, September 2026 among them (20). Public release notes with an RSS feed, support through a ticket portal and a docs feedback tool. No public issue tracker or community forum was read (10). Client SDKs are current. The MCP server isn't in the official MCP registry, and no API client library was found (10). The SDK repositories and their CI weren't read (5). Total 75. The checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance): - 0 to 30, time since the last release, or the last published model or API change for a closed service. 30 within 30 days, 20 within 90, 10 within 180, 0 older. - 20, at least three releases or dated changelog entries in the last 90 days. - 0 to 25, responsiveness. Issues and pull requests answered on GitHub (the open issues and how recent the replies are). For closed services, a public changelog and a support or community channel that answers, 0 to 15. - 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models). - 10, package health, current dependencies and CI. Models are read for deprecation notice periods and model churn rather than release counts. ## 6. Transparency & trust, 75 out of 100, up to 2.2 more on the total Made of editorial 60, provenance 89. Why it scored 75: Closed service. The published Terms of Use are short and undated, and the Master Service Agreement that the acceptable use policy refers to isn't public (13). A public DPA, a privacy policy dated 26 August 2026 that covers MoEngage as processor, an SLA that states backups every 12 hours kept for 3 months, and an AI policy that commits to no training of third-party models on customer data. Retention periods sit in a help centre article that wasn't read (22). No API deprecation policy was found. The docs say legacy API keys will be deprecated, with no date, and that the early access Flows endpoints won't receive breaking changes (5). The sub-processor list, last modified 1 September 2026, gives each processor's service and location, and the docs name the region of each data centre (20). Total 60. The checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency): - 0 to 30, source availability and licence clarity. 30 for open source under an OSI licence, 15 for closed with clear terms, 0 for unclear terms. - 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors). - 0 to 20, a deprecation policy or notices with dates. - 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted). The other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two. Provenance checks not met in full (half of this category, computed from checked facts): - Terms of service: read, states 6 of the 7 things a reader expects (9.1 of 10) - security.txt: not found (0 of 10) ## 7. Schema & documentation, 87 out of 100, up to 2.1 more on the total Why it scored 87: 36 OpenAPI 3 files are linked from the docs index, with 140 operations on 119 paths and 535 schemas (25). The docs publish llms.txt, llms-full.txt, a Markdown twin of every page, a skill.md file and a docs MCP server (10). All 140 operations have a summary and a description, and the MCP page states what each tool can't do, but few descriptions say when not to use an endpoint (16). The files carry 503 enums and required lists, while 121 of 1,132 object schemas have no declared properties (12). There are 1,725 example entries, 400 or 401 on every operation and 429 on 103 (14). Versions are mixed (v1, v2, v2.1, v5 and a dated 2025-11-20 campaigns file). Monthly product release notes list new APIs and SDK changelogs are dated, but no API changelog was found (10). Total 87. The checklist (https://www.anchorterminal.com/benchmark/#checklist-schema): APIs and MCP servers. - 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool). - 10, llms.txt or Markdown docs served for agents. - 0 to 20, descriptions that say what a tool is for, when to use it and when not to, read from the tool definitions in the source or the API reference. - 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs. - 0 to 15, examples and documented error responses. - 15, versioning and a public changelog. Models are read from the API reference, the OpenAPI file, llms.txt, the structured-output and tool-use docs and the model cards. Frameworks from docs a model can follow, typed interfaces, examples and the API reference. ## What we couldn't check What we couldn't read counted as absent. Publishing it on a page a plain HTTP fetch can read (not only in a browser) lets the next check count it. - unchecked: https://www.moengage.com/security/ answered 403 and wasn't retried, and trust.moengage.com wasn't read, so certifications are taken from the scale and security page - unchecked: the MCP tool definitions, their input schemas and any readOnlyHint or destructiveHint annotations, which need a signed-in session. The tool count of 52 is from the docs tables - unchecked: audit log coverage of API and MCP calls. Audit logs appear on the pricing page as a plan item and no docs page for them was read - unchecked: the data archival policy on help.moengage.com that the SLA cites for retention periods - unchecked: MoEngage's GitHub repositories, so stars, CI and issue handling for the SDKs are not recorded - The Master Service Agreement isn't published, so provenance.terms points at the Terms of Use, which say they govern the website and related software and services - Monthly product release notes carry no day, so lastRelease is the Android SDK changelog entry of 9 October 2026 - The lead gave https://moengage.com/docs/developer-guide/ as the docs link. That is the SDK guide. The API reference is at /docs/api/introduction, and the lead didn't mention the hosted MCP server - Scores follow the generally available REST API, with the hosted MCP server counted where the checklist asks about tools ## Weaknesses - No public price, free tier or trial. The pricing page lists Growth and Enterprise plans with a one-year minimum and a sales contact only - On 17 August 2026 the Inform API in DC-03 returned HTTP 200 for about 16 hours while some messages were never sent, per the status page - Scoped keys, OAuth 2.0 and AWS STS keys sit in an API key dashboard that is in early access and enabled on request - Segmentation and Inform accept Basic authentication only, and new Push API keys can't be created - No API deprecation policy was found, and no official server-side API client library was found in the documentation ## What costs an agent a turn today The notes we give agents before they call it. Each one is a workaround an agent shouldn't need. - Take the data centre number from the dashboard URL and call `https://api-{dc}.moengage.com`. Data can't be moved between data centres - Send an `Idempotency-Key` header (UUID v4) on V5 campaign writes and test sends, and a `transaction_id` on Inform alerts, which deduplicates for 5 minutes - Use internal event and attribute names in segment filters, and run `deep_validate_segment_filters` first. A wrong event name is accepted and the count later fails with no reason - Use `in` with a list for text equality in segment filters. `equals` returns a 400 that names no field - Reuse an OAuth access token until it nears expiry. The token endpoint allows 5 requests a minute and 30 per 10 minutes for each key ## When it's done Send what changed and where it's published as a dispute (https://www.anchorterminal.com/builders/#disputes, or `POST https://www.anchorterminal.com/api/v1/contact` with `"kind": "dispute"`). Disputes are answered in public, and the listing is checked again by the same checklist. Paying for an audit or a listing claim changes nothing here.
