Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# helius-mcp

MCP (Model Context Protocol) server that exposes Helius/Solana data tools for AI assistants.

## Directory Structure

```
src/
  index.ts             # Entry point — MCP server setup, tool registration
  tools/               # Tool definitions (one file per tool group)
    balance.ts
    assets.ts
    transactions.ts
    webhooks.ts
    network.ts
    wallet.ts
    ...
  utils/
    helius.ts          # SDK client wrapper — getHeliusClient(), rpcRequest(), dasRequest(), restRequest()
```

## Tool Registration Pattern

Each tool file exports a `register*Tools(registry: ActionRegistry)` function that registers its actions with `registry.registerAction(name, description, inputSchema, handler)` (see `src/router/action-registry.ts`). Tool modules never register on the MCP server directly: their handlers are collected in `src/router/action-handlers.ts` and reached through the 10 routed public tools in `src/router/register.ts`. Handlers take `(args, extra)`; pass `extra` to `contextFromExtra`. Tools use the helius-sdk `createHelius()` for SDK methods and `restRequest()`/`rpcRequest()`/`dasRequest()` for non-SDK endpoints.

## SDK vs Raw Fetch

How to install

The exact contents, by fingerprint

mdr add helius-labs/core-ai/helius-mcp/CLAUDE.md@sha256:821796bbfc089d8b

The line at the top of this page pins the label git:20261028.b91252d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
