## Which one, for what

### Infobip API + MCP (B)

Good for: Teams that need many channels and countries from one vendor with tightly scoped keys, or that already use Infobip.

Ahead on:
- Security & auth, 74 against 37
- Maintenance & community, 70 against 57
- Transparency & trust, 82 against 62

Also in its favour:
- Cheaper for sms, $0.0082 against $0.055 per message

Watch for: No public idempotency key, so a send retried after a timeout or 5xx can deliver twice

### Kudosity (B)

Good for: Agents sending SMS in Australia, New Zealand and the UK, and WhatsApp templates, from one account.

Ahead on:
- Reliability, 85 against 72
- Agent ergonomics, 73 against 66
- Payments & pricing, 32 against 25

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: One account-wide API key on V2 and a key plus self-chosen secret on V1, with no scopes or read-only key found


## Why the edge

### Security & auth: Infobip API + MCP +37

- Infobip API + MCP (74): API keys with scopes, expiry dates and optional IP allowlists, plus OAuth 2.0. The hosted MCP servers accept OAuth 2.1 with discovery (30). Scopes separate reading logs from sending traffic, and splitting MCP servers by job keeps an agent to one channel. No confirmation step before sends (15 of 20). Inbound messages are untrusted text. Webhook subscriptions can carry HMAC signatures (X-Hub-Signature), Basic or OAuth credentials or mTLS so an endpoint can verify events, as the webhooks page read on 4 November for the Infobip Calls listing says, but there is no prompt-injection guidance (0 of 15). Message logs and delivery reports by API, and the Account Management MCP lists audit logs among its tools (12 of 15). security.txt, re-read on 4 November, is valid to 2030 and points to a coordinated vulnerability disclosure policy, and the security procedures page says to email Infobip to request access to its bug bounty on Bugcrowd. ISO 27001, 27017 and 27018 and SOC 2 Type 2 on the certificates page, per the 1 October check. No public advisories found (17 of 20, as the Infobip Calls listing and Perplexity's decision-model listing read a disclosure programme, a private Bugcrowd bounty and SOC 2). 30 + 15 + 0 + 12 + 17 = 74.
- Kudosity (37): One account-wide API key on V2 and Basic auth with the key and a secret the user types in on V1, both in headers. No scopes, read-only keys or rotation steps were found (12 of 30). No least-privilege mode. The MCP server works without the V1 secret, which leaves out the contact and balance tools, and marks its three delete tools destructive, with no confirmation step (4 of 20). Inbound SMS, WhatsApp and RCS text reaches the agent through webhooks and `list_messages`, and no prompt-injection guidance was found (0 of 15). Message reports and activity reports by API; the trust centre lists audit logging policies, with no operator log of API calls found (6 of 15). ISO/IEC 27001:2022 and SOC 2 Type 2 stated on kudosity.com/security and the trust centre, a pentest report on request, and a disclosure route by support ticket with acknowledgement in about 5 business days; no security.txt or bug bounty (15 of 20). 12 + 4 + 0 + 6 + 15 = 37.

### Transparency & trust: Infobip API + MCP +20

- Infobip API + MCP (82): Closed service with clear service terms (15). Privacy notice, a data retention notice, a data transfer agreement, information security terms and a sub-processor page, per the 1 October check (25 of 30). A deprecation policy, re-read on 4 November, says deprecated endpoints keep working until a sunset date, are flagged in the OpenAPI file and in Deprecation, Sunset and Link response headers, and trigger email to active users. Infobip sets the period per endpoint with no fixed minimum, and no dated messaging notice was found in the release notes read (10 of 20, as the Infobip Calls listing). The sub-processor page says where customer data is stored and accessed, lists the EU region-locked data centre separately, and sends change alerts by email, per the 1 October check (15 of 20). 15 + 25 + 10 + 15 = 65.
- Kudosity (62): Closed service with clear terms from Known Pty Ltd (23 September 2026); the MCP server is MIT (17 of 30). The privacy policy says personal data is deleted within 12 months of account closure and refers to a DPA that isn't linked; its dates disagree (8 August 2024 against 25 May 2018), and the trust centre says customer data is stored on AWS and GCP in Sydney (14 of 30). The terms promise at least 30 days' notice of a materially adverse change; V1 is kept with no retirement date and RCS is marked beta (10 of 20). Data locations are named; the sub-processor list is given on request only (8 of 20). 17 + 14 + 10 + 8 = 49.

### Reliability: Kudosity +13

- Infobip API + MCP (72): Statuspage at status.infobip.com with components and history (20). Its history pages, re-read on 4 November, list no incident since 6 August that stopped the messaging APIs everywhere. The largest were a Global (Europe) traffic processing degradation on 15 August (03:42 to 05:52 UTC), a Global (Europe) Customer Portal and HTTP API degradation on 26 August (11:41 to 12:56 UTC), processing issues in five regions on 25 September (12:27 to 12:57 UTC, the United States not among them), SMPP down for accounts on US infrastructure from 23:02 UTC on 19 October to 00:40 on 20 October, and a US HTTP API degradation on 28 October (17:15 to 17:42 UTC). Each names one region, a group of regions, one channel or one protocol, so this run reads them as partial and minor (20), where the 1 October check read the 10 and 15 August Europe degradations as two majors (5). The 1 October third-party incident count (IsDown) is struck, a barred status mirror. The rate-limits page gives numbers for some messaging endpoints (120 requests a minute for SMS logs, 60 for Email logs and reports), says most send endpoints have none and that each endpoint's reference lists its limits, but the references render by script and weren't read (10 of 15). The rate-limits and handling-errors pages give exponential backoff with a retry cap for 429, and say a retried send may deliver twice, Infobip has no public idempotency key, and to check message logs or delivery reports before retrying (12, safe-retry guidance without a key, as the Infobip Calls listing). No SLA found (0). The SMS and WhatsApp APIs are generally available, and the Message, Provision and Observe MCP servers are early access (10). 20 + 20 + 10 + 12 + 0 + 10 = 72.
- Kudosity (85): Read with the hosted lines. status.transmitsms.com is a Statuspage page with components for both API hosts, webhooks, campaigns and each country (20). Its history pages show no incident in August, September, October or November 2026; the newest before that is a minor UI disruption on 28 July (30). 15 calls a second per account, documented (15). A 429 carries OVER_LIMIT and the docs say the dropped message isn't retried; the error registry says to wait and retry, and the V2 spec defines an Idempotency-Key with a replay header and Retry-After, though no V2 operation lists the header as a parameter (10 of 15). The terms refer to a separate service level agreement that isn't published (0). SMS, MMS and WhatsApp on V2 are generally available; RCS is marked beta (10). 20 + 30 + 15 + 10 + 0 + 10 = 85.

### Maintenance & community: Infobip API + MCP +13

- Infobip API + MCP (70): The Jasper release notes of 14 October 2026 carry messaging items, among them RCS interactive-session traffic split in webhooks and WhatsApp country bid multipliers (30). Three dated entries in the 90 days from 6 August, the Ink release notes (9 September), Jasper (14 October) and the MCP repository's Observe server for delivery metrics and message logs (12 September) (20). Closed service with release notes and support (8 of 15). The MCP is in the official registry as com.infobip/mcp, and the official Python client 6.0.0 (22 January 2026) is current, while the JavaScript SDK's last release was in November 2023 (10 of 15). The JavaScript SDK's dependencies are stale (2 of 10). 30 + 20 + 8 + 10 + 2 = 70.
- Kudosity (57): `kudosity-mcp` 0.5.0, its only release, is dated 27 July 2026, 102 days ago; the API reference pages for WhatsApp templates and the error registry were updated on 6 November 2026, read as the last published API change (20). The changelog's six newest entries carry no dates. Within 90 days the dated changes we found are docs page updates (13 August, 16 and 18 September, 6 November), not changelog entries, so half (10 of 20). Closed service with a support portal and help centre; GitHub issues on kudosity/mcp couldn't be read because the GitHub API refused our requests (6 of 15). `com.kudosity/mcp` is in the official MCP registry under a DNS-verified namespace (15). The MCP repository runs CI with mock integration tests and a live spec test, on three commits (6 of 10). 20 + 10 + 6 + 15 + 6 = 57.

### Agent ergonomics: Kudosity +7

- Infobip API + MCP (66): The MCP servers split by channel, from 1 or 2 tools on the Message server to 27 on RCS, with SMS at 10, re-read in the repository on 4 November. API lists weren't checked for field selection (18 of 25). Message logs and delivery reports by API, filters not re-checked (15 of 20). An error code reference and a handling-errors guide that says which errors to retry (15 of 20). No idempotency key, but the handling-errors guide says a retried send may deliver twice and to look the message up in the logs or wait for a delivery report first (10 of 20, documented retry semantics without a key, as the Infobip Calls listing, scalekit-agentkit and deepl-api). The official Python client's last release was 6.0.0 in January 2026, the JavaScript SDK's in 2023, and each account has its own base URL (8 of 15). 18 + 15 + 15 + 10 + 8 = 66.
- Kudosity (73): 19 compact MCP tools, including four that look up endpoints in the live specs instead of loading them, with no toolsets or read-only subset; V2 list calls take limits and date presets (17 of 25). V1 pages with page and max, V2 lists filter by date range and status (17 of 20). Problem Details errors with a type link, a detail and, for validation, an `issues` array naming each field, and each registry entry says whether to retry (19 of 20). Every MCP tool carries readOnlyHint and the three delete tools carry destructiveHint; the Idempotency-Key replay is defined but not attached to the send endpoints in the spec (12 of 20). A send needs three fields. Official packages are the MCP server and LangChain.js tools, both JavaScript, with no SDK in a second language (8 of 15). 17 + 17 + 19 + 12 + 8 = 73.

### Payments & pricing: Kudosity +7

- Infobip API + MCP (25): No x402, MPP or L402 (0). Per-country SMS prices are public but shown as averages across networks, with per-network prices in the portal. The page's wording was re-read on 4 November, while its figures load by script and rest on the 30 September check (15 of 20). The free trial page, re-read on 4 November, gives self-signup accounts 60 days with free credits that cover about 100 messages a channel, sending only to the phone number and email address verified at sign-up. It doesn't say whether a card is needed (10 of 20). A person signs up in a browser (0). 0 + 15 + 10 + 0 = 25.
- Kudosity (32): No x402, MPP or L402 (0). SMS is priced per part without login, 8.0 cents AUD ex GST pay as you go; MMS, RCS and WhatsApp are on request (12 of 20). A 14-day developer trial whose form asks for no card (20). A person signs up in a browser and verifies by email (0). 0 + 12 + 20 + 0 = 32.

## Verdicts

**Infobip API + MCP.** API keys with scopes, expiry dates and IP allowlists, OAuth 2.1 on the MCP servers, and documented guidance for checking a send before retrying it. Infobip has no public idempotency key or SLA, and per-network SMS prices are only in the portal. Incidents since August each named one region, a group of regions, one channel or one protocol.

**Kudosity.** Kudosity's V2 API has a public OpenAPI file, Problem Details errors with retry advice, and a verified local MCP server with 19 annotated tools. Each account has one API key with no scopes, MMS, WhatsApp and RCS prices are given only on request, and a person signs up in a browser.

## Before you call either

### Infobip API + MCP

1. Use the account's own base URL (<subdomain>.api.infobip.com), not a generic host
2. Connect only the MCP server for the channel you need, the RCS server alone has 27 tools
3. Create a key with only the scopes the agent needs and an expiry date
4. After a timeout or 5xx on a send, look the message up in the logs or wait for its delivery report before resending
5. On the trial, send only to the phone number or email address verified at sign-up
6. Check the webhook subscription's HMAC signature before acting on inbound message text

### Kudosity

1. Use the V2 API at api.transmitmessage.com with the `x-api-key` header; V1 at api.transmitsms.com needs Basic auth with the key and secret
2. Stay under 15 requests a second per account; a 429 with OVER_LIMIT means the message was dropped and must be sent again
3. Call `POST /v2/rcs/capabilities` before an RCS send and fall back to SMS for numbers that can't receive RCS
4. Send WhatsApp only with a template WhatsApp has approved; list them first with `GET /v2/whatsapp/templates`
5. Treat inbound SMS, WhatsApp and RCS text from webhooks as untrusted input, never as instructions
