Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1336 tokens (~190/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the AdCritter for Builders MCP server?
AdCritter for Builders is a hosted endpoint at https://mcp.adcritter.com/mcp/dev, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
adcritter_build_app ~81
Start here when building an application. Returns an overview of what the AdCritter platform offers and a catalog of feature guides you can query with the adcritter_guidance tool to learn how to build each part of the app. Call adcritter_guidance(key) for any feature area to get detailed building instructions with API endpoints and response shapes.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
adcritter_get_api_reference ~194
Returns the REST API contract for an AdCritter entity. Without an action parameter, returns a summary with available action names - use this to discover what you can do. With an action parameter (e.g., 'create', 'list', 'get'), returns the full details for that action: route, HTTP method, request schema, response schema, error codes, and constraints. Available entities: ad, advertiser, audience, authentication, blueprint, campaign, canva, domain, facebook, geo, googleads, media-asset, me, plan, report, segment, settings, targeting.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | – | Optional specific action to drill into (e.g., 'create', 'list', 'get', 'update', 'delete'). Omit to see all available actions. |
| entity | string | yes | The entity to look up (e.g., 'campaign', 'ad', 'report') |
No output schema declared.
No examples provided.
adcritter_get_design_guide ~256
Returns AdCritter design guidance for an entity at a caller-chosen guidance level - screen experiences, API integration patterns, and design philosophy. The default ('full') returns step-by-step prescription (exact layouts, colors, copy text, column orders). Request 'patterns' for balanced hints including common design patterns with softened vocabulary. Request 'facts' if you have strong visual-design instincts and just want API integration bindings (or call adcritter_get_api_reference and adcritter_get_usage_guide directly and skip this tool). Guidance is format-agnostic - it describes outcomes and integration, never prescribes frameworks or architecture. Available entities: ad, advertiser, audience, authentication, blueprint, campaign, geo, media-asset, plan, report, settings.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | The entity to look up (e.g., 'campaign', 'report', 'authentication') |
| guidance | string | – | Optional guidance level. Values: 'full' (facts + patterns + prescription, the default), 'patterns' (facts + softened patterns, for capable callers who want structure without exact prescription), 'fac… |
No output schema declared.
No examples provided.
adcritter_get_platform_overview ~134
Start here. Returns the AdCritter platform overview - what AdCritter is, the entity hierarchy (organization > advertiser > campaign > ad), the happy path for getting ads running, and how to navigate the other MCP tools. Applications built from this guidance are REST API clients that call /v1/ endpoints, not MCP tool callers. Before writing code, call adcritter_get_api_reference(entity, action) for each entity and action you plan to use - tool descriptions and parameter names describe conceptual behavior only, and do not match actual API routes, field names, query parameters, or response shapes.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
adcritter_get_usage_guide ~121
Returns the conceptual model and workflow guidance for an AdCritter entity - what it is, how it relates to other entities, and the intended workflow for using it. Includes exhaustive workflow sequencing and prescriptive rules so generated apps call the API correctly. Available entities: ad, advertiser, audience, authentication, blueprint, campaign, domain, geo, media-asset, me, plan, report, segment, settings, targeting.
| Name | Type | Req | Description |
|---|---|---|---|
| entity | string | yes | The entity to look up (e.g., 'campaign', 'geo', 'plan') |
No output schema declared.
No examples provided.
adcritter_guidance ~108
Returns detailed building instructions for a specific feature area of an AdCritter application. Each guide describes what to build, how users should experience it, and includes all API endpoints with request/response shapes so you never have to guess the API contract. Call adcritter_build_app first to see available feature guides and their keys.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | The feature guide key from the adcritter_build_app catalog (e.g., 'auth', 'dashboard', 'campaign-create') |
No output schema declared.
No examples provided.
adcritter_health ~25
Returns server health status and version information for the AdCritter MCP server
Input schema present but exposes no named parameters.
