Create a webhook endpoint

webhookEndpoints_create

Create a delivery target for monitor events. kind=http requires a public HTTPS url; kind=sink is a hosted test inbox with no url. The signing secret is returned once — store it now.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlNo
kindYes
contextYesDescribe the user's underlying goal in one sentence — not the tool you are calling.
llm_modelYesThe exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
descriptionNo
conversation_idNoEcho the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it.

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only provide readOnlyHint=false and openWorldHint=false, leaving the description to carry the behavioral burden. The description adds valuable non-obvious disclosures: the signing secret is returned only once and should be stored immediately, and http vs sink have different url requirements. This goes beyond the schema and annotations, though it does not mention idempotency or persistence details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the core purpose, then the critical kind-specific constraints and the secret warning. Every clause earns its place with no filler or repetition of the schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the essential creation behavior, the two kind variants, and the most important output detail (one-time signing secret), which is especially useful given there is no output schema. It does not describe the full response shape, but for a create endpoint the critical return value is highlighted.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%, so the description must compensate for undocumented parameters like kind and url. It does so clearly: kind=http requires a public HTTPS url, while kind=sink has no url. The description also reinforces the one-time signing secret behavior, which relates to the output rather than a parameter, but the key parameter semantics are well handled.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: "Create a delivery target for monitor events," and distinguishes the two kinds of endpoints (http vs sink). This clearly separates it from sibling tools like webhookEndpoints_update, webhookEndpoints_delete, and webhookEndpoints_test.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the use case: creating a webhook endpoint for monitor events, and gives concrete guidance for choosing kind=http vs kind=sink. However, it does not explicitly contrast with alternative activities like updating, testing, or deleting endpoints, so the routing guidance is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.4/5.0
Disambiguation5/5

Each tool is clearly scoped to a specific platform and action (e.g., facebook_post_get vs instagram_post_get). Descriptions explicitly differentiate similar tools across platforms, and within-a-platform tools like tiktok_search_videos_list vs tiktok_search_hashtag_list have clear disambiguation notes.

Naming Consistency5/5

All 167 tools follow a strict `platform_resource_action` pattern (e.g., youtube_video_comments_list). No mixing of styles—snake_case throughout, with consistent verb ordering (get, list, search, etc.).

Tool Count2/5

The server has 167 tools, which is far beyond the typical well-scoped range of 3-15. While the broad multi-platform scope justifies many tools, this extreme number makes the tool surface overwhelming and difficult for an agent to navigate efficiently.

Completeness4/5

The tool set covers a wide range of platforms and operations including profile retrieval, post/video fetching, comments, search, transcripts, and ad library access. Minor gaps exist (e.g., no Facebook events or LinkedIn messaging), but the surface is comprehensive for a read-only data aggregation use case.
