Pi coding agent support + clearer tool description

Pi coding agent users can now install the Chainstack skill: curl -o ~/.agents/skills/chainstack/SKILL.md https://mcp.chainstack.com/skill. All MCP server tools work via Pi's bash and the public HTTP endpoint.
Pi uses the Skill route only — Pi rejects MCP servers by design. The discovery page at mcp.chainstack.com now flags this so Pi users skip the wrong setup path.
Discovery page description now mentions pricing and testnet funds. Agents reading mcp.chainstack.com see the full tool surface: deploy and manage blockchain nodes, search protocol docs and RPC references, check platform status, get pricing, request testnet funds, and reach Chainstack's team.

New tool: get_chainstack_pricing

Ask your agent anything about Chainstack pricing and get an answer grounded in live data — no guessing, no stale quotes.
Covers plan tiers (Developer through Enterprise + Pay As You Go), the feature matrix, add-on pricing (Unlimited Node, Yellowstone gRPC, Warp transactions), and the full per-chain dedicated-node catalog (~87 user-orderable SKUs with regions, hardware flavors, hourly and monthly USD prices).
Regions come with a slug → city legend (sgp1 → Singapore, fra1 → Frankfurt, etc.).
No API key required. Every call fetches fresh from the public pricing sources — the server holds zero hardcoded pricing data, so changes on chainstack.com show up immediately.
Example prompts: "I expect 50M RU/month and need archive data — which plan fits?", "How much is a dedicated Ethereum archive node in London?", "Pro + Unlimited Node 250 RPS + 1000 Warp transactions — total monthly?"

New tool: request_testnet_funds

Top up testnet addresses with gas for EVM, Solana, or TON development — directly from your agent.
12 networks: Ethereum Sepolia, Ethereum Hoodi, Base Sepolia, Polygon Amoy, BNB testnet, zkSync Sepolia, Scroll Sepolia, HyperEVM testnet, Plasma testnet, Monad testnet, TON testnet, Solana devnet.
The faucet tops an address up to the per-network cap — it doesn't send a fixed amount. If the address is already at the cap, the call fails.
API key required. Rate-limiting is tracked per organization (24h cooldown).
On cooldown, the error includes nextFaucetAvailable (ISO 8601) so agents can tell you exactly when to retry.

New tool: contact_chainstack

Reach out to Chainstack directly from your agent for anything — sales, support, or general questions.
No API key required. Agent asks for confirmation before sending; PII is redacted from server logs.
