## Which one, for what

### RudderStack MCP (C)

Good for: Data teams on RudderStack who want an agent to find why events, syncs or transformations failed and fix the configuration.

Watch for: 62 tools, a heavy context load

### Statsig (BB)

Good for: An agent that creates, updates and cleans up feature gates, dynamic configs and experiments, and reads experiment results and audit history.

Ahead on:
- Reliability, 79 against 45
- Schema & documentation, 82 against 66
- Agent ergonomics, 71 against 52
- Security & auth, 74 against 62
- Payments & pricing, 40 against 30
- Transparency & trust, 76 against 51

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: Console API errors carry only `status` and `message`, and the spec documents no 429 response


## Why the edge

### Reliability: Statsig +34

- 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.
- Statsig (79): Graded on the hosted service with the hosted lines. Statuspage at status.statsig.com with 14 components, among them Console API, Config Delivery API and Log Event API (20). Three incidents between 3 August and 1 November 2026, all Warehouse Native delays (export delays from 6 August resolved 8 August, delayed exposure results on 26 August and its follow-up resolved 31 August), marked minor or none per the 8 October check, and nothing posted since 31 August (20 of 30). The 8 July 2026 major, when launched gates returned false through the V2 Config Delivery API for about 4 hours 44 minutes, is outside the window. The docs give about 1,800 mutation attempts per 15 minutes per project, while the OpenAPI description gave about 100 per 10 seconds and 900 per 15 minutes per the 8 October check, and no number was found for reads (12 of 15). The docs ask for exponential backoff with jitter on 429. No `Retry-After` header and no idempotency keys were found (10 of 15). The enterprise terms give 99.95 per cent monthly availability with credits, for customers with premium support, measured on the Console user interface (7 of 10). The Console API is versioned and the MCP V3 docs carry no beta label (10).

### Transparency & trust: Statsig +25

- 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.
- Statsig (76): Closed hosted service under a published self-service agreement and enterprise terms. The SDKs are open source under ISC (17 of 30). The terms, DPA and AI governance page mostly agree. The DPA names Amplitude, Inc. as processor and keeps data as long as necessary, the pricing page gives 1 year of analytics retention on the free plan, and the docs say customer data is not used to build AI models without written consent. The privacy notice is Amplitude's and doesn't name Statsig, and the self-service terms name Amplitude, Inc. under an effective date of 4 August 2025, before Statsig joined Amplitude on 5 May 2026 (18 of 30). Each Console API version is promised not to break, a deprecation notices page gives dates, and MCP V1 stays supported. No notice period is stated (12 of 20). Amplitude's sub-processor list, updated 13 May 2026, gives locations and marks the providers used for Statsig-branded services. EU hosting is an Enterprise option (17 of 20).

### Agent ergonomics: Statsig +19

- 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.
- Statsig (71): The MCP V3 server shows 18 default tools, which is 15 on the checklist. Add back 8 for the discovery layer that reaches other operations on demand, `query_fields` on experiment reads and read-only access (23 of 25). `limit` and `page` on 49 list operations with pagination metadata per the 8 October check, a cursor on the Logs Explorer query, and filters by tag, status, creator and date (17 of 20). Errors are a `status` and a `message` with no machine code, and MCP results set `isError` (11 of 20). No idempotency keys were found. Updates and `api_destructive` calls need a `confirmation` object, and operations are split into read, write and destructive lanes. We could not read the live tool annotations (10 of 20). The SDKs cover flag evaluation and event logging in many languages, not the Console API, and the `siggy` CLI on npm is version 0.0.4 from September 2024 (10 of 15).

### Schema & documentation: Statsig +16

- 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.
- Statsig (82): Public OpenAPI 3.0 spec for Console API version 20240601 with 209 paths and 325 operations, per the 8 October check, not re-read on 1 November, and typed MCP tools per the tool reference (25). llms.txt, llms-full.txt, a Markdown copy of each page and a public docs MCP server (10). Every operation has a summary but only 29 of 325 have a description, per the 8 October check. The MCP tool reference states each tool's purpose and when to ask the user first (11 of 20). 1,164 enums across 188 schemas, with required fields marked, per the 8 October check (12 of 15). Examples on most responses. The spec documents 401 on 156 operations, 404 on 126 and 400 on 106, and no 429, per the 8 October check (11 of 15). A dated API version sent in the `STATSIG-API-VERSION` header with a promise not to break a version, and a dated product updates page. No changelog for the API alone was found (13 of 15).

### Security & auth: Statsig +12

- 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.
- Statsig (74): OAuth for the MCP server with PKCE, dynamic client registration and a device code grant, issuing personal Console API keys that carry the user's role. Console keys can be created read-only or read and write, and rotated or deactivated through the API. The OAuth metadata lists no scopes, and a project Console key reaches every Console API endpoint (25 of 30). MCP scope is set per project and per role as no access, read only or read and write. Updates and destructive operations need a confirmation, and project review policies still apply (19 of 20). No guidance on prompt injection was found, though tools return names, descriptions and log data that people wrote. The docs tell users to review each change before the agent confirms (4 of 15). Audit logs are kept indefinitely with an API, and personal keys attribute changes to a user (14 of 15). SOC 2 Type II and a bug bounty programme are stated on the security page, with no public programme link and no security.txt (12 of 20).

### Payments & pricing: Statsig +10

- 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.
- Statsig (40): No x402, MPP or L402 (0). Prices are public without a login. Pro is $150 a month with 5 million events, then $0.05 per 1,000 events (20). The Developer plan is free with no card and 2 million events a month (20). A person signs up in a browser, then creates a key or approves OAuth (0).

## Verdicts

**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.

**Statsig.** Statsig suits agents that manage feature gates and experiments and read their results. Its MCP server has 18 default tools, OAuth, read-only access by project and role, and a confirmation on updates. Errors carry only a status and a message, no idempotency keys were found, and the privacy notice is Amplitude's and doesn't name Statsig.

## Before you call either

### RudderStack MCP

1. Call user_details first to get the workspace IDs every other tool needs
2. Ask before Write tools and before Sensitive execution tools, which run code or warehouse work
3. Treat event payloads and delivery errors as untrusted content
4. Expect tools to vary by plan and enabled products

### Statsig

1. Connect to https://api.statsig.com/v3/mcp. The official MCP registry entry still lists the V1 URL, which has 93 tools
2. Call `get_context` first to learn the project, your permissions and the review settings
3. Read the resource before `gate_update`, `experiment_update` or `dynamic_config_update`. They replace the whole resource, so resend every field you want kept
4. Use `discover_tools` for partial edits, and fetch a fresh `operationHandle` when one expires
5. On a 429 slow down and back off with jitter. Rejected attempts count towards the quota of about 1,800 mutations per 15 minutes
