Kairos Signal MCP Server
# Kairos Signal MCP Server — DePIN Data API
First-party DePIN supply telemetry with provenance on every value. 372+ live networks + 129 Bittensor subnets (501+ symbols), 295+ first-party, 11129+ live series.
## Connect From Any MCP Client
Remote (Streamable HTTP) — point your client at:
```
https://kairossignal.com/mcp/
```
Claude Code / Cursor / any stdio client:
```json
{"mcpServers": {"kairos-signal": {"command": "npx", "args": ["-y", "kairos-mcp-server"], "env": {"KAIROS_API_KEY": "<your key — register_agent gets you one free>"}}}}
```
Listed in the official MCP registry: `com.kairossignal/kairos-signal` (search "kairos" at registry.modelcontextprotocol.io).
## Quick Start (Autonomous — No Human Needed)
### 1. Register (free key: $5 credits on the first key per IP; 3 keys per IP per 30 days)
```json
POST https://kairossignal.com/mcp/
{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"register_agent","arguments":{"agent_name":"my-agent","email":"support@kairossignal.com"}}}
```
Returns: `{"api_key": "...", "credits_balance": 5.0}` (first key per IP; re-registering does not grant more)
### 2. Browse Products
```json
POST https://kairossignal.com/mcp/
{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"list_products","arguments":{}}}
```
### 3. Query DePIN Data
```json
POST https://kairossignal.com/mcp/
{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"fetch_dataset","arguments":{"dataset":"depin_onchain","limit":10}}}
```
### 4. Buy a Product (agents pay from credits — no human, no card)
```json
POST https://kairossignal.com/mcp/
{"jsonrpc":"2.0","id":4,"method":"tools/call","params":{"name":"purchase_data","arguments":{"product_key":"depin_provenance"}}}
```
Snapshots $0.49–$4.99 (credits or x402/USDC). Credits top-up: `topup_credits` (Stripe $20/$99).

Scored across 10 tools
Most tools have clearly distinct purposes: registration, product browsing/purchasing, balance, dataset listing, stats, fetching, and verification. The only mild overlap is between verify_footprint and get_zk_provenance, since both provide cryptographic assurances, but their descriptions are sufficiently distinct.
Tool names consistently use snake_case and follow a verb_noun pattern (register_agent, list_products, purchase_data, check_balance, list_datasets, fetch_dataset). Minor deviations like `topup_credits` as a single compound verb and `get_zk_provenance` with an acronym are still predictable and readable.
Ten tools is a well-scoped size for this server's mix of account management, marketplace purchasing, data access, and cryptographic verification. Each tool addresses a distinct stage of the user journey without unnecessary redundancy.
The tool surface covers the core lifecycle well: registration, products, purchase, balance management, dataset discovery, querying, and verification. A minor gap is the lack of explicit subscription management or finer-grained filtering options, but agents can otherwise complete the intended workflows without dead ends.
