## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-28.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint returned HTTP 503.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).

### 2026-09-22 (score 65)

First indexed and scored.

## MCP tools (10)

### `agentobserver_interfaces` (~28 tokens)

Discover all public AgentObserver interfaces: HTTP/x402, MCP/x402 and A2A.

### `agentobserver_targets` (~40 tokens)

Legacy registered-target catalog: list free status actions and any target-specific paid eligibility. Use agentobserver_dependencies/agentobserver_resolve for the primary dependency workflow.

### `agentobserver_dependencies` (~63 tokens)

Discover x402 dependencies agents already use, including Exa Search, BlockRun, OneSource, Apify, Laevitas and others. Returns endpoint-specific demand evidence when available.

Input parameters:

- `capability`: Optional exact capability filter such as web-search, market-data or automation.

### `agentobserver_resolve` (~118 tokens)

Resolve providers for a capability using factual filters and dated demand evidence. Sorting is not a trust score.

Input parameters:

- `capability` (string, required): Capability the calling agent needs.
- `include_degraded` (boolean): Include providers explicitly observed as unreachable/dead. Default false.
- `limit` (integer): Maximum providers returned.
- `max_price_usd`: Optional maximum listed resource price in USD.
- `network`: Optional payment network such as eip155:8453.
- `sort_by` (string): Objective ordering basis, not a recommendation.

### `agentobserver_spend_status` (~89 tokens)

Check one dependency before spending. Use for Exa Search, BlockRun Chat Completions, OneSource, Apify or any catalog resource; never sends provider credentials or payment signatures.

Input parameters:

- `live` (boolean): Run a safe unsigned live probe when the registry explicitly allows it.
- `provider_id` (string, required): Catalog provider identifier.
- `resource_id` (string, required): Provider resource identifier.

### `agentobserver_check_before_spend` (~145 tokens)

Use immediately before invoking or paying a dependency. Checks Exa Search, BlockRun, OneSource, Apify, Laevitas or any AgentObserver catalog resource for current observable terms, endpoint-specific demand and drift without sending credentials or payment signatures.

Input parameters:

- `live` (boolean): If true, run the safe unsigned live observation when the catalog explicitly allows it.
- `provider_id` (string, required): Dependency provider id, for example exa, blockrun, onesource, apify or laevitas.
- `resource_id` (string, required): Dependency resource id, for example search, chat-completions, deepstate-markets, x402-prepaid-token or instruments.

### `agentobserver_dependency_watch` (~52 tokens)

Read persisted continuous-watch state for an eligible dependency. This tool never triggers an outbound probe.

Input parameters:

- `provider_id`: Optional provider id.
- `resource_id`: Optional resource id; supply together with provider_id.

### `agentobserver_status` (~59 tokens)

Free preflight status: show freshness, reachability, material changes and factual reasons that deserve review before relying on or paying a registered counterparty.

Input parameters:

- `target` (string, required): Registered AI-agent counterparty URL to inspect before relying on or paying it.

### `agentobserver_dependency_preflight` (~71 tokens)

Paid x402 dependency Preflight for eligible resources such as OneSource, BlockRun Exa Find Similar, Apify and Laevitas. Returns fresh hash-bound pre-spend evidence.

Input parameters:

- `provider_id` (string, required): Catalog provider identifier.
- `resource_id` (string, required): Eligible catalog resource identifier.

### `agentobserver_preflight` (~72 tokens)

Paid x402 Preflight: return fresh machine-readable evidence about a registered AI-agent counterparty.

Input parameters:

- `max_age_seconds` (integer): Maximum acceptable evidence age in seconds; use a smaller value for stricter freshness.
- `target` (string, required): Registered AI-agent counterparty URL whose fresh evidence should be purchased.
