summary: >-
  Two MCP surfaces exist and they are different things. (1) FIRST-PARTY, LOCAL-STDIO: the operator
  publishes `scalpstream-mcp`, a Go MCP server (binary `scalpmcp`) that a user installs and runs
  locally; it wraps the five x402 data services and pays for each call from the user's own
  wallet (USDC on Base), with hard per-call and per-process spend caps; with no key configured
  every paid tool returns the free preview plus the quoted price. Ownership is established by the
  sibling repo DV1-321/agent-cards, which exists to prove that GitHub account's namespace over the
  ScalpStream agents. (2) PLATFORM-AUTHORED, REMOTE: www.scalpstream.com/_api/mcp is the Wix Site
  MCP that Wix serves for every Wix site; tools/list answered 200 with Wix's generic 9-tool set
  (GetBusinessDetails, SearchInSite, CallWixSiteAPI ...). It is reachable and unauthenticated, but
  it exposes the marketing site, not the data APIs, and the operator did not write it - recorded
  so the difference is visible, not credited as an operator-built remote server.
deployment:
  mode: local-stdio

  note: >-
    No hosted https endpoint for the first-party server is published anywhere (README, agent
    cards, x402 docs, llms.txt all point only at the local binary). The MCP client config is
    {"command":"scalpmcp","env":{EVM_BASE_PRIVATE_KEY, SCALPMCP_MAX_PRICE_USD, SCALPMCP_BUDGET_USD}}
    - omit env entirely for preview-only mode. verified: searched (read from the repo and Go
    module proxy, not executed).

payments:
  model: x402 (client-side)
  note: >-
    The server pays sellers per call from the user's Base-mainnet key held in process memory;
    gas is facilitator-sponsored so the wallet needs only USDC. Defaults SCALPMCP_MAX_PRICE_USD
    0.10 and SCALPMCP_BUDGET_USD 2.00 are enforced before signing; an unset limit means the
    default, never unlimited; spend is recorded only when data is delivered.

tools_note: >-
  Tool names and descriptions are transcribed from the repository README's Tools table; input
  schemas were not enumerated (that requires installing and running the binary). RecallScout is
  NOT among the eight tools in the v0.1.6 README even though it is one of the five A2A agents -
  recorded as a gap between the MCP surface and the A2A surface, not corrected.

    Byte-identical to the Wix tool set found on 38 other Wix tenants in the catalog (see the
    platform-authorship audit). It serves site content and Wix business APIs for the marketing
    site; none of the five data services are reachable through it. Not the provider's server.
