Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agentobserver
agentobserver_check_before_spend
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.
agentobserver_dependencies
Discover x402 dependencies agents already use, including Exa Search, BlockRun, OneSource, Apify, Laevitas and others. Returns endpoint-specific demand evidence when available.
agentobserver_dependency_preflight
Paid x402 dependency Preflight for eligible resources such as OneSource, BlockRun Exa Find Similar, Apify and Laevitas. Returns fresh hash-bound pre-spend evidence.
agentobserver_dependency_watch
Read persisted continuous-watch state for an eligible dependency. This tool never triggers an outbound probe.
agentobserver_interfaces
Discover all public AgentObserver interfaces: HTTP/x402, MCP/x402 and A2A.
agentobserver_preflight
Paid x402 Preflight: return fresh machine-readable evidence about a registered AI-agent counterparty.
agentobserver_resolve
Resolve providers for a capability using factual filters and dated demand evidence. Sorting is not a trust score.
agentobserver_spend_status
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.
agentobserver_status
Free preflight status: show freshness, reachability, material changes and factual reasons that deserve review before relying on or paying a registered counterparty.
agentobserver_targets
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 - Check x402 Dependencies Before Paying — questions

Answers built from our own checks of this server.

What can AgentObserver - Check x402 Dependencies Before Paying do?
It exposes 10 tools, read directly from the server on our last check. Among them: agentobserver_check_before_spend, agentobserver_dependencies, agentobserver_dependency_preflight, agentobserver_dependency_watch, agentobserver_interfaces, agentobserver_preflight and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is AgentObserver - Check x402 Dependencies Before Paying working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 371 ms. The bar chart above shows every period we have measured.
The registry lists AgentObserver - Check x402 Dependencies Before Paying as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect AgentObserver - Check x402 Dependencies Before Paying?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does AgentObserver - Check x402 Dependencies Before Paying need an API key?
No. AgentObserver - Check x402 Dependencies Before Paying completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
