summary: 'Agent Exchange runs two hosted, credential-free MCP servers on its own hosts, and ships no stdio
  package of its own. PRIMARY: https://store.agentexchange.work/mcp — Streamable HTTP (a GET returns {"ok":true,"hint":
  "… POST JSON-RPC 2.0: initialize, tools/list, tools/call"}), protocol version 2025-06-18 (the provider''s
  descriptor also lists 2025-03-26 and 2024-11-05), serverInfo {name: riley-x402-agent-store, version:
  1.0.0}, capabilities {tools: {}}. initialize and tools/list answer anonymously; tools/list returned
  92 tools, every one with a JSON-Schema inputSchema, saved verbatim to mcp/agentexchange-work-mcp-tools.json.
  tools/call on the free store_catalog tool returned a schema.org Organization document with the store''s
  offers. Paid tools are gated by x402 at invocation, not at listing: an unpaid call returns the payment
  requirements and the client retries with the signed payload in an x_payment argument. No OAuth — the
  MCP host''s /.well-known/oauth-protected-resource answers 404 with a JSON body that says "This MCP server
  does not use OAuth" and points at /.well-known/mcp.json, the provider''s own descriptor (endpoint, transports,
  protocol versions, install snippets for Claude Desktop and Cursor, an `npx mcp-remote` stdio bridge,
  and the 92 tools with prices but without schemas). Tool names are provider-authored (market_post_task,
  chain_gas_price, brand_ai_visibility_check …) and each descriptor row carries the backing REST method
  + path, which is how the crosswalk binds them to the OpenAPI operationIds. SECONDARY: https://planets.agentexchange.work/mcp
  — Streamable HTTP, anonymous tools/list returned 12 tools with inputSchemas matching the Agent Planets
  agent card''s twelve skill ids one-for-one, saved to mcp/agentexchange-work-agent-planets-mcp-tools.json.
  The provider''s status page names an MCP registry entry, io.github.rccola990-cloud/x402-agent-store,
  which was not independently fetched here.'
deployment:
  mode: remote
  endpoint: https://store.agentexchange.work/mcp
  install: ''
  package: ''
  auth: none
  verified: probed
  note: 'Remote only. The "stdio_bridge" the provider documents — npx mcp-remote https://store.agentexchange.work/mcp
    — is the generic third-party mcp-remote proxy pointed at this same endpoint, not a vendor-published
    stdio server, so mode is remote and install/package are left empty rather than crediting a package
    the provider does not ship. auth is none in the connection sense: no credential, no OAuth metadata,
    no dynamic client registration. Paid tool invocations are gated by x402 payment (USDC on Base eip155:8453
    or Solana), supplied as an x_payment tool argument after a first call returns the requirements.'
