persimmon
Registry code: b24f1aa5219c6d71
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.

- Is persimmon live?
- Yes — it answered the hub's last check (checked 7m ago). It answered 100% of checks over the last 30 days.
- Is persimmon free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does persimmon have?
- 3 tools: get_brand_signals, get_competitive_context, get_momentum_index.
- Is persimmon safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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_competitive_context reads open 3h ago
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.
{ "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 linesget_momentum_index reads 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.
{ "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 linesget_brand_signals reads 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.

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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idb24f1aa5219c6d71.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
