Kairos Signal MCP Server — verifiable DePIN data

Measured supply-side telemetry for DePIN (decentralized physical infrastructure) networks: GPU and compute capacity, storage, node and hotspot counts, on-chain totals. 365+ networks with live data (from a catalog of 720+ entries) plus 129 Bittensor subnets: 495+ live symbols, 310+ networks read first-party, 18,700+ live series. Figures are floors; live counts: GET https://kairossignal.com/v1/networks.

Every value carries source, as_of and a verify_url on the network's own API, and the verify_value tool re-reads that upstream for you and says where the same number appears.

Connect

Remote endpoint (Streamable HTTP). The read-only tools need no key:

Cursor, Windsurf and other clients that take a URL:

json

{"mcpServers": {"kairos-signal": {"url": "https://kairossignal.com/mcp"}}}

VS Code (.vscode/mcp.json):

json

{"servers": {"kairos-signal": {"type": "http", "url": "https://kairossignal.com/mcp"}}}

Any stdio client, through this package's bridge:

json

{"mcpServers": {"kairos-signal": {"command": "npx", "args": ["-y", "kairos-mcp-server"]}}}

Paid depth is optional: send your key as an X-API-Key header (remote) or KAIROS_API_KEY (bridge).

Official MCP Registry: com.kairossignal/kairos-signal. The server negotiates MCP 2025-11-25, 2025-06-18, 2025-03-26 and 2024-11-05, and every tool carries a title and behaviour annotations.

Ask it things

Question	Tool calls
What is Akash's GPU capacity right now?	`find_networks {"query": "akash"}` → `get_network {"symbol": "AKT", "metric_filter": "gpu"}`
How did Filecoin's active miners move this week?	`get_metric_history {"symbol": "FIL", "metric": "ACTIVE_MINERS"}`
Is that number real?	`verify_value {"symbol": "FIL", "metric": "ACTIVE_MINERS"}`

verify_value fetches the value's verify_url now and reports the JSONPath where the same number appears, the relative difference and a verdict (exact, within_1pct, within_10pct, no_matching_field, not_checkable_by_get). A real result from 2026-10-07:

json

{"symbol": "AKT", "metric": "GPU_ACTIVE", "verdict": "within_1pct",
 "match": {"json_path": "$.resources.gpu.active", "upstream_value": 297.0, "relative_difference": 0.003378}}

Tools

Tool	What it returns	Key
`find_networks`	networks by name or ticker → symbol, name, category, page	no
`get_network`	latest first-party values for one network, each with unit, `as_of`, freshness and `verify_url`	no
`get_metric_history`	daily series for one metric (free tier: last 7 days)	no
`verify_value`	re-reads the upstream now; JSONPath, difference and verdict	no
`get_stats`	row count per dataset, free-tier limits	no
`get_data_dictionary`	freshness, history depth and coverage per feed	no
`get_derivation_ledger`	archived raw upstream payloads and collector code hashes	no
`list_datasets`, `fetch_dataset`	raw rows (free tier: newest 10 per query)	no
`verify_footprint`	Merkle inclusion check for one archived row	no
`register_agent`	API key plus free starter credits ($5 on each of the first 3 keys per IP per 30 days)	—
`list_products`, `purchase_data`, `topup_credits`, `check_balance`	paid data products bought with prepaid credits	yes

Paid data (optional)

register_agent {"agent_name": "my-agent"} returns an API key. The $5 starter credits apply to the first 3 keys per IP per 30 days; past that a key is still created, at $0, and the response says so. email is optional.
list_products lists every product and its live price.
purchase_data {"product_key": "depin_provenance", "api_key": "<your key>"} charges your credits and delivers the data in the same response.
topup_credits returns a Stripe checkout link ($20 or $99), or a USDC-on-Base quote after wallet verification (https://kairossignal.com/docs/crypto.html).

Pricing

Free key: $5 credits (first 3 keys per IP per 30 days). One-shot products: $0.49–$29.99 (list_products for the live catalog). Design Partner: $199/mo. Pro: $499/mo. Enterprise: $2,000+/mo.
