# MCP packages

> Six protocol-specific MCP servers Graph Advocate routes to. All free, all npx-installable, all reading The Graph directly — no Graph Advocate call required.

Graph Advocate routes to **six protocol-specific MCP servers**. Every one is free, installs with `npx`, and reads The Graph directly with your own API key. You do not need to call Graph Advocate to use them — routing you *to* them is the point.

<Note>
  These are alternatives, never the primary answer. Each is a thin wrapper around subgraphs and REST APIs an agent can call directly. The MCP packages the calls with friendly tool names and saves you writing the GraphQL — that is the whole value, and it is a real one.

## The packages

| Package                | Covers                                                                              | Install                    |
| ---------------------- | ----------------------------------------------------------------------------------- | -------------------------- |
| `graph-aave-mcp`       | Aave V2/V3/V4 — 40+ tools, including cross-chain liquidation risk                   | `npx graph-aave-mcp`       |
| `graph-uniswap-mcp`    | Uniswap V2/V3/V4 — 8 tools over 13 subgraphs, 6 chains                              | `npx -y graph-uniswap-mcp` |
| `graph-polymarket-mcp` | Polymarket — 35 tools, live CLOB + on-chain analytics + CLOB V2 builder attribution | `npx graph-polymarket-mcp` |
| `graph-lending-mcp`    | Cross-protocol lending via Messari standardized subgraphs                           | `npx graph-lending-mcp`    |
| `graph-limitless-mcp`  | Limitless prediction markets on Base                                                | `npx graph-limitless-mcp`  |

Most need a free Graph API key from [thegraph.com/studio](https://thegraph.com/studio/) in `GRAPH_API_KEY`.

<Note>
  **Retired packages.** `predictfun-mcp` (2026-08-05), `substreams-search-mcp` (2026-08-11) and
  `create-substreams-sink-sql` (2026-08-17) were unpublished from npm — their `npx` commands 404.
  Use the underlying surfaces instead: the [Predict.fun REST API](https://dev.predict.fun/)
  (testnet `api-testnet.predict.fun/v1/markets` is keyless), the public Substreams registry
  `GET substreams.dev/v1/registry/packages?query=<term>`, and `substreams sink postgres|clickhouse`
  from the Substreams CLI.

## Uniswap

```bash theme={null}
GRAPH_API_KEY=your_key npx -y graph-uniswap-mcp
```

Eight tools across **13 subgraphs** — V2, V3 and V4 on Ethereum, Base, Arbitrum, Polygon, Optimism and BSC. Subgraph-ID addressed and schema-adaptive, so a subgraph version bump does not break it.

Good for: *"Top Uniswap V3 pools on Base by volume"*, *"Compare WETH/USDC liquidity across V2, V3 and V4"*.

For **derived** Uniswap answers — pre-trade liquidity checks, spot-vs-perp basis, per-wallet accumulation — see [Uniswap pre-trade & flow](/uniswap). Those are paid endpoints because they assemble something the raw subgraph does not contain. The basis JOIN in particular has no MCP equivalent: it spans two venues.

## Aave

```bash theme={null}
GRAPH_API_KEY=your_key npx graph-aave-mcp
```

40+ tools over Aave V2, V3 and V4, including cross-chain liquidation risk and V4 hub/spoke topology. Good for: *"Top Aave V3 markets by TVL on Ethereum"*, *"Recent Aave liquidations above \$50K"*.

## Polymarket

```bash theme={null}
npx graph-polymarket-mcp
```

35 tools spanning the Gamma and CLOB REST APIs and the Polymarket subgraphs — live prices, order books, trader P\&L, UMA resolution status. As of v2.1.1 it also covers **CLOB V2 builder attribution**, which answers "which frontend routed this flow" — a question no V1 contract emits the data for.

## Lending, Limitless, Predict.fun

`graph-lending-mcp` compares protocols through Messari's standardized schema, so Aave and Compound become directly comparable. `graph-limitless-mcp` covers Limitless on Base. `predictfun-mcp` covers Predict.fun on BNB Chain and needs no key at all.

## Machine-readable

Every package above is declared in Graph Advocate's capability catalog with its install command, auth requirement and example prompts:

```bash theme={null}
curl -s https://graphadvocate.com/agents/capabilities.json \
  | jq '.capabilities[] | select(.interface | test("MCP"))'
```

That endpoint is the source of truth — this page is generated from the same metadata.
