Connect AI agents to the Pulse Verity MCP server

Vendor MCP

The Pulse Verity MCP connector routes your AI agent's tool calls to Pulse Verity's own MCP server through Scalekit. Each user signs in to Pulse Verity once, and Scalekit stores and refreshes their tokens, so your agent never handles credentials. It comes with 9 tools.

Setup

Install the SDK
- Node.js
- Python
Terminal window
npm install @scalekit-sdk/node dotenv
Terminal window
pip install scalekit-sdk-python python-dotenv
Set your credentials
Add your Scalekit credentials to your .env file. Find values in app.scalekit.com > Developers > API Credentials.

```
Create the Pulse Verity MCP connection
In AgentKit > Connections, create a Pulse Verity MCP connection. The name you give it is the connection_name your code passes. See Configure connections.
Scalekit credentials are available for Pulse Verity MCP server, so you don't need to register an OAuth app.

pulseveritymcp_get_account_statusRead this connection's Pulse Verity plan and usage from /api/index/v1/account: plan, used (calls counted this UTC month), limit, remaining, resetAt, perMinute, batchMaxSymbols, capacityAction and upgradeUrl (the plans page).Read-only
Get Pulse Verity Account Status
Read this connection's Pulse Verity plan and usage from /api/index/v1/account: plan, used (calls counted this UTC month), limit, remaining, resetAt, perMinute, batchMaxSymbols, capacityAction and upgradeUrl (the plans page). The monthly allowance is account-wide: every key and connected app on the account shares it. perMinute applies to each key. This call does not count toward the allowance.
Inputs
This tool takes no inputs.
pulseveritymcp_get_index_batchRead signed prices for up to 100 symbols per request; this account's plan may allow fewer (get_account_status reports batchMaxSymbols).Read-only
Get Pulse Verity Index Batch
Read signed prices for up to 100 symbols per request; this account's plan may allow fewer (get_account_status reports batchMaxSymbols). One /api/index/v1/batch request returns observations with individually signed successful rows and per-symbol errors for unavailable rows. A request over the plan's limit is refused with code TOO_MANY_SYMBOLS: split it. Verify each successful row with verify_print; the v2 block on each row signs its quality fields, while the surrounding batch metadata is not signed. No automatic retries.

pulseveritymcp_get_index_historyRead price history for one crypto symbol from /api/index/v1/history: candles (open, high, low, close) at 1m, 5m, 1h or 1d, with period metrics and pagination.Read-only
Get Pulse Verity Index History
Read price history for one crypto symbol from /api/index/v1/history: candles (open, high, low, close) at 1m, 5m, 1h or 1d, with period metrics and pagination. dataset=verified (default) is built from prints Pulse signed live; reconstructed is rebuilt history at 1h or 1d and was not signed at the historical time. The account's plan sets whether history is included and how far back a request reaches: rangeClamped says the window was shortened, and historyLimit names the plan when the plan did it. Each call counts as one API call. For the next page pass pagination.nextCursor as cursor with the same symbol, dataset and interval. Signed rows (verifiedObservations) are returned only with includeSignedRows=true; each verifies with verify_print. Candles and metrics are not signed. An empty page means no recorded history in that window, never a zero price.
Inputs

Crypto ticker symbol, e.g. BTC
assetIdstring
Canonical asset id, when a ticker names more than one asset.

Start, ISO-8601 or epoch milliseconds (13 digits); 30 days before `to` when omitted. The plan may shorten it.

pulseveritymcp_get_index_priceGet a current signed crypto index price from /api/index/v1/price.Read-only
Get Pulse Verity Index Price
Get a current signed crypto index price from /api/index/v1/price. Returns symbol, price, optional priceText, at, grade, signature, kid and sig. Preserve priceText exactly for verify_print. Optional tier, confidence, dispersionBps, interval, sources, engine and cadence describe the observation; they are not covered by the v1 signature, and the v2 block signs them with the price. Pass the whole print, v2 included, to verify_print. Coverage changes: use list_index_assets to discover assets. A stale or unavailable response means no current price, never zero.
Inputs
symbolstringrequired
Crypto ticker symbol, e.g. BTC, ETH, SOL
pulseveritymcp_get_recorded_printGet the recorded signed index print nearest a requested time from /api/index/v1/print.Read-only
Get Recorded Print
Get the recorded signed index print nearest a requested time from /api/index/v1/print. Accepts ISO-8601 or epoch milliseconds. Check deltaMs: it is the distance between your requested time and the sampled print. Sampling and retention are bounded; a recorded print need not equal a separate live read. qualityRecorded says whether its quality fields were stored when it was recorded (prints from 1 Oct 2026). Preserve priceText, kid and the v2 block when present for verify_print. deltaMs is not signed. Formerly named get_settlement_print; calls under that name still work.

Get Pulse Verity Upgrade Options
List the Pulse Verity plans with their limits and prices, and the prepaid call packs and extra stream connections while each is on sale, each with a portal link. Read-only; does not count toward the allowance. The current plan is marked when the account is on that plan's terms (currentPlan shows the account's own limits either way), and when a recent plan refusal is known (or reason is given) the smallest plan, add-on or pack that fixes it is recommended. A link opens the portal, which shows the item, price and terms; the account holder completes payment on Stripe. Nothing is bought by this tool or by opening a link.

List Pulse Verity Index Assets
Read one bounded page from /api/index/v1/verity/catalog. Discover crypto symbols and their current coverage status and measured cadence. Catalog rows, prices and metadata are unsigned: use get_index_price or get_index_batch for signed receipts. Availability changes; total is a catalog count, not a count of fresh prices. No automatic pagination.

pulseveritymcp_verify_printVerify a signed print locally with ECDSA P-256/SHA-256.Read-only
Verify a Signed Print
Verify a signed print locally with ECDSA P-256/SHA-256. Canonical bytes are pulse-index-v1\n<symbol>\n<priceText or String(price)>\n<at>\n<grade>. The public key ring is read from /api/index/v1/pubkey, cached for five minutes and refreshed at most once per 30 seconds on a failed check. A supplied kid selects only that exact key; old prints without kid are tried against the bounded published ring. valid=true authenticates only the canonical price fields, not kid, sig, quality, cadence, timestamps outside at, or other metadata. When the print carries a v2 block (pulse-index-v2), it is verified too: v2.valid=true means the signature over v2.canonical is valid AND every signed line (sources, tier, confidence, dispersionBps, interval, cadence, engine, price and the rest) matches the supplied fields; v2.signedFields are the signed values and v2.mismatches names any field that differs. recordValid=true and verificationScope=full-record require BOTH price and complete v2 record verification. metadataSigned equals recordValid. Require recordValid before trusting quality fields. A v1-only print has scope price-only, never verified metadata. Neither signature proves freshness or settlement suitability; indicative data must not be used for settlement. An invalid signature can mean an altered print or a key no longer published; it does not by itself prove tampering.

Submit Verity Feedback
Write one structured bug, missing capability, or data quality report for private human triage. Only submit when the user requests reporting; do not include keys, passwords, transcripts or attachments. For a price problem, add quote: the price, at and source exactly as you received them, and grade, signature and kid from the print when you have it; with a signature the server checks the quote against Verity's published keys, so triage can tell a real Verity print from an altered or foreign one. Returns a durable receipt and duplicate flag, not a promise of a fix. No code or production behavior changes automatically. Status is available with the same account at GET /api/index/v1/feedback/<id>.
