+## Blockchain RPC (Tooling Access)
+
+`call-rpc` sends a read-only JSON-RPC request through the account's Tooling Access setting, which covers every network Quicknode supports. No endpoint provisioning, URL, or token handling. The server mints and refreshes the short-lived credential per call. This is the same account setting behind `qn rpc call` in the CLI and the `rpc` client in the SDK, so enabling it once covers all three.
+
+### Inputs
+
+| Input | Required | Description |
+|-------|----------|-------------|
+| `method` | Yes | JSON-RPC method name, e.g. `eth_blockNumber`, `getSlot`, `getblockcount` |
+| `network` | Yes | Tooling Access network slug, e.g. `ethereum-mainnet`, `solana-mainnet`, `btc` |
+| `params` | No | JSON-RPC params as JSON text, e.g. `["0xabc...", "latest"]` |
+
+One tool covers every chain family: `eth_getBalance` on `base-mainnet`, `getSlot` on `solana-mainnet`, and `getblockcount` on `btc` all route through `call-rpc`.
+
+### Network Slugs
+
+Use the network slugs `list-chains` returns. If the server rejects a slug, the error lists every slug it accepts; read the accepted list from that error rather than guessing. `qn rpc list-networks` prints the same list from the CLI.
+
+### Read-Only Enforcement
+
+Only registered read-only methods are allowed. A write method is rejected before it reaches the chain:
+
+```text
+RPC method eth_sendRawTransaction is not allowed. Only registered read-only methods may be called.
+```
+
+To send transactions, provision a dedicated endpoint (`create-endpoint`) and sign and broadcast from application code.
+
+### Enabling And Disabling
+
+`enable-tooling-access` turns the setting on for the account. `disable-tooling-access` turns it off. Both take no arguments and are idempotent, and both require the **Admin** role. A Viewer connection can call `call-rpc` once Tooling Access is on, but cannot turn it on; if `call-rpc` fails because the setting is off, ask the user to reconnect with Admin or enable it from another interface.
+
+`disable-tooling-access` is account-wide: it cuts off RPC access for every Quicknode developer tool on the account, including the CLI and the SDK, not just the current assistant. Confirm with the user before calling it.
+
+The same setting is readable and writable over REST at `/v0/tooling-access`. See [admin-api-reference.md](admin-api-reference.md) for status, enable/disable, and token-minting details.
