MCP Tools Reference

The ChainStream MCP Server exposes the full data catalog and DeFi primitives as Model Context Protocol tools. This page is the authoritative reference — for how to register the server with Claude, Cursor or other clients see MCP Server Setup.

Endpoint

URL: https://mcp.chainstream.io/mcp
Transport: Streamable HTTP (horizontal scaling + progress reporting)
Auth: Bearer token (X-API-KEY) or x402 micropayment (USDC on Base / Solana)

Two tool surfaces

ChainStream ships the MCP server in two flavours. Pick the one that matches your agent’s workflow.

Surface	Naming	When to use
Outcome-oriented tools	`tokens_search`, `dex_swap` (underscore)	Agents doing user-facing tasks — each tool orchestrates several REST calls and returns a curated result. This is what the Agent Skills reference.
Playground tools	`getToken`, `createEndpoint` (camelCase)	1:1 coverage of the REST API for programmatic use — same inputs/outputs as REST, ideal for testing and low-level automation

The 17 outcome-oriented tools below are what you see in the production MCP catalog. Playground tools are the full REST surface re-exposed as MCP tools — listed at the bottom.

Resources

URI	Content
`chainstream://chains`	Supported chains and status
`chainstream://chains/{chain}/dexes`	DEX protocols for a chain
`chainstream://docs/api_reference`	Full REST API reference (all `/v2/*` endpoints)
`chainstream://docs/query_examples`	Common query patterns for agents

Risk model

Each tool is tagged with a risk level. Clients should surface tools with level ≥ L2 behind explicit confirmation UI.

Level	Meaning
L0	Read-only, stateless — safe to call automatically
L1	Read-only, user-scoped (wallet profile, webhook list) — safe but personal
L2	Read-only but computationally expensive (backtest) — may incur cost
L3	Writes / signs / broadcasts — always requires explicit user confirmation

Outcome-oriented tools (17)

Token intelligence

Tool	Description	Key params	Risk
`tokens_search`	Search tokens by name, symbol or address across every supported chain	`query`, `chain?`	L0

`tokens_price_history`	OHLCV candlestick data for charting and technical analysis	`chain`, `address`, `resolution`, `from?`, `to?`	L0
`tokens_discover`	Find tokens by on-chain metrics (volume, price change, trade count)	`chain`, filters	L0
`tokens_compare`	Side-by-side comparison of up to 5 tokens	`chain`, `addresses[]`	L0

Wallet intelligence

Tool	Description	Key params	Risk
`wallets_profile`	Complete wallet profile — holdings, PnL and net worth in one call	`chain`, `address`	L1
`wallets_activity`	Recent wallet transfers and balance changes	`chain`, `address`, `limit?`	L1

Market discovery

Tool	Description	Key params	Risk
`market_trending`	Trending tokens by category (`hot`, `new`, `migrated`, `graduating`, `stocks`)	`chain`, `category`, `duration`	L0
`trades_recent`	Recent on-chain trades for a token or wallet	`chain`, `token?`, `wallet?`, `limit?`	L0

DEX and trading

Tool	Description	Key params	Risk
`dex_quote`	Swap quote with expected output, price impact and fees (read-only)	`chain`, `from`, `to`, `amount`	L0
`dex_swap`	Execute a token swap on a DEX	`chain`, `from`, `to`, `amount`, `slippage`	L3
`dex_create_token`	Create a token on a launchpad	`chain`, `name`, `symbol`, `dex`, `uri`	L3
`trading_backtest`	Backtest a strategy against historical data	strategy spec	L2
`trading_execute`	Execute a strategy trade	`chain`, `strategy`, `params`	L3
`transaction_send`	Broadcast a signed transaction	`chain`, `signed_tx`	L3

Ops

Tool	Description	Key params	Risk
`webhooks_manage`	Manage webhook endpoints (list, create, delete)	`action`, endpoint spec	L1
`blockchain_info`	Supported chains and DEX protocols	—	L0

KYT / compliance is not wrapped as an outcome tool — call the REST API directly under /v1/kyt/*. See KYT concepts.

Playground tools (REST-parity)

The Playground surface mirrors the REST API 1:1 as MCP tools. Every tool accepts the same JSON parameters as the corresponding REST endpoint and returns a content[0].text JSON string with the raw response. Use these when you want programmatic parity with REST but routed through MCP.
