Kairos Signal — verifiable DePIN data API

Kairos Signal MCP Server — DePIN and world data

Measured DePIN telemetry, physical-world datasets and descriptive research analytics through REST and MCP. Use source links, observation times and coverage metadata to decide whether a result is suitable for your question. Availability and freshness vary by feed.

Kairos Signal is not a property-owner contact or lead-generation service. The current product is data and research, not a promise of profitable trading signals.

Coverage changes. Use find_networks, get_data_dictionary and the network catalog rather than a copied network count. Catalog entries, distinct networks, Bittensor subnets, rows and metric series are different quantities. get_stats describes dataset row counts, not network coverage.

Full MCP endpoint (Streamable HTTP):

https://kairossignal.com/mcp

Read-only edition, without account creation, purchases or payment tools:

https://kairossignal.com/mcp/public

Read-only does not mean every tool is anonymous or free. In either edition, get_network_signals requires an eligible paid-tier key with the engines capability. Other discovery/data tools have their stated no-key samples and limits. The full edition also exposes account tools and paid analytics.

Claude Code:

claude mcp add --transport http kairos-signal https://kairossignal.com/mcp

Cursor, Windsurf and clients that accept a URL:

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

VS Code (.vscode/mcp.json):

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

Stdio clients can use this package's bridge:

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

Key placement depends on the tool:

• get_network_signals requires an eligible subscription key in the connection's X-API-Key header. Tiered network/history access also uses that header. In the stdio bridge, KAIROS_API_KEY supplies the header.
• Paid analytics accept that header or an api_key tool argument.
• purchase_data, topup_credits and check_balance require api_key inside the tool input, even when the connection or bridge already has a header key. The bridge does not inject it into the arguments.

An API key, a credit balance and a subscription entitlement are not interchangeable.

Official MCP Registry identity: com.kairossignal/kairos-signal. Prefer the vendor endpoint above over a third-party proxy. Smithery's October 31, 2026 service notice says its proxy and connection-management services will close while its directory remains.

Ask a measured question

• GPU capacity: find_networks {"query":"akash"}, then get_network {"symbol":"AKT","metric_filter":"gpu"}.
• Observed history: get_metric_history {"symbol":"FIL","metric":"ACTIVE_MINERS"}. An absent series is not a zero.
• Check a figure: verify_value {"symbol":"FIL","metric":"ACTIVE_MINERS"}. Read the verdict; some upstream values cannot be checked by a GET.

Tools and access

The bridge obtains tools/list from the hosted service rather than maintaining a separate implementation. Consult that live schema for current inputs, prices and limits.

Tool	Purpose	Access / effect
get_network_signals	Scheduled Hodge/lag-relation snapshots for configured market, DePIN and world cohorts. Descriptive, not a trading recommendation.	Eligible paid-tier key with engines capability in the connection header
find_networks	Find networks or subnets by name or ticker. Resolve ambiguous tickers before use.	No key
get_network	Latest supported first-party network measurements, with provenance and freshness fields.	No key
get_metric_history	Observed daily history for one metric; gaps are not zero-filled.	No key for the free window; paid tiers have different limits
verify_value	Compare with a supported upstream GET response, which may be cached; inspect upstream.read_at_utc and the verdict.	No key
register_agent	Create an API key; starter credits are conditional on the current per-IP policy.	Creates an account/key
list_products	Product descriptions, prices and deliverability information.	No key
purchase_data	Purchase an eligible product; delivery can be inline or a receipt with a retrieval URL.	api_key in tool input and sufficient credits
topup_credits	Request a supported card-checkout link or USDC quote; follow current payment instructions.	api_key in tool input; obtaining a quote is not a confirmed payment
check_balance	Read the account credit balance.	api_key in tool input
list_datasets	Current dataset catalog.	No key
get_stats	Dataset row counts, scope and free-tier limits; not a count of distinct networks.	No key
get_data_dictionary	Coverage, observation freshness, history depth and endpoints per feed.	No key
get_derivation_ledger	Index of covered archived fetches and their payload/code hashes; raw payload bytes are a separate product.	No key
fetch_dataset	Raw archive rows within the applicable query limits. Rejected or unchecked observations can be retained.	No key for the free sample
verify_footprint	Merkle membership for a supported retained observation; not proof of upstream accuracy or zero-knowledge computation.	No key
get_hodge_regime_sieve	Hodge decomposition of metric lead-lag flows; the historical tool name does not imply regime classification.	Paid per answered call
get_rmt_regime_state	Correlation-spectrum comparison with a Marchenko–Pastur reference; not a calibrated regime test.	Paid per answered call
get_depin_slashing_audit	Enforcement-capacity calculation from sourced protocol parameters; bounds and unavailable inputs remain explicit.	Paid per answered call
get_shap_node_attribution	Day/unit Shapley decomposition of observed metric changes; not causal attribution or a forecast.	Paid per answered call
get_listing_dilution_score	Measured token-supply changes; not an exchange-listing or investment score.	Paid per answered call

Paid analytics can spend credits. Read the current description before calling; do not repeatedly invoke a paid tool to retry an uncertain result. Their historically named identifiers are retained for compatibility, not as claims of forecasting or causal validation.

Provenance: what the checks establish

Supported network measurements expose provenance and observation-time fields. A source URL is a way to inspect an origin, not a guarantee that the origin is correct. History, derived analytics, raw archives and catalog metadata have different response contracts; do not assume that every output is a fresh first-party measurement.

verify_value compares against a supported upstream GET response that may be cached; inspect upstream.read_at_utc and the verdict rather than assuming a new upstream fetch. verify_footprint checks retained Merkle membership, not upstream truth, independent Bitcoin confirmation or a zero-knowledge proof. The derivation ledger covers the fetches it explicitly lists; a network can have live telemetry without an archived derivation entry. Raw archives can retain rejected or unchecked observations—read their quality fields.

Products, delivery and pricing

Use list_products and the live credit catalog for current prices, eligibility and deliverability; use the pricing page for subscription access. This documentation does not set prices or payment policy.

• Registration creates a key; starter-credit eligibility depends on the current per-IP policy. Read the returned balance instead of assuming a grant. A starter key does not itself grant paid-tier engine access.
• purchase_data requires api_key in its tool input and a currently deliverable product. Small responses can arrive inline; larger deliveries return a receipt and retrieval URL. Use your own stable idempotency_key for each intended purchase and reuse it only for retries of that purchase.
• The current catalog describes dag_manifold_30d as a DAG API access product. Listed legacy/retired products are not automatically purchasable; read deliverability before committing credits.
• topup_credits provides payment instructions for supported card and USDC modes. A quote or checkout link is not payment confirmation. Follow the payment documentation; never send funds without a successful current quote.
