api record

Persimmon brand-intelligence MCP from Spann. Three read-only tools: get_momentum_index, get_brand_signals, get_competitive_context. Every response is filtered through the evidence-policy egress filter; internal-only and licensed-display content is dropped before emit.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 3 tools
1 open 2 never probed 1 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_momentum_index open 3h ago

    Use this when an agent needs Persimmon's deterministic momentum score for a specific brand or the top of the index. Returns composite score plus four dimensions (Draw, Surge, Wedge, Hold), tier band, signal count, and last-updated timestamp. Pure read; no LLM calls in scoring.

    mcp-tool

    {
  "type": "object",
  "required": [],
  "properties": {
    "brand": {
      "type": "string",
      "description": "Brand name. Omit to receive the full index (capped to top-N by composite score)."
    },
    "limit": {
      "type": "integer",
      "maximum": 200,
      "minimum": 1,
      "description": "When `brand` is omitted, cap the number of returned brand entries. Defaults to 50. Maximum 200."
    }
  },
  "additionalProperties": false
}
    arguments 17 lines
  • get_competitive_context unknown never probed

    Use this when an agent needs a brand's competitor set, peer momentum snapshots, and a deterministic competitive-position one-liner. Excludes peers without real signal coverage (scaffold tier). Always carries a coverage_status describing the result.

    mcp-tool

    {
  "type": "object",
  "required": [
    "brand"
  ],
  "properties": {
    "brand": {
      "type": "string",
      "description": "Brand name."
    },
    "limit": {
      "type": "integer",
      "maximum": 10,
      "minimum": 1,
      "description": "Max number of peer snapshots to return. Defaults to 4."
    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • get_brand_signals unknown never probed

    Use this when an agent needs the recent harvested signals (each with text, tier, score, and source URL) backing a brand's score. Public-citable signals only — internal-only items are filtered before emit. Always carries a coverage_status describing why a list may be empty.

    mcp-tool

    {
  "type": "object",
  "required": [
    "brand"
  ],
  "properties": {
    "brand": {
      "type": "string",
      "description": "Brand name."
    },
    "limit": {
      "type": "integer",
      "maximum": 50,
      "minimum": 1,
      "description": "Max signals to return. Defaults to 10."
    },
    "tier_floor": {
      "enum": [
        "NOTABLE",
        "STRONG"
      ],
      "type": "string",
      "description": "Minimum signal tier to include. Defaults to NOTABLE."
    }
  },

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
