What get_protocol_tvl does on Tanod
AI agents call get_protocol_tvl to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
chain | object | — | Chain name, e.g. Ethereum, Base, Solana, BSC, Arbitrum (common aliases such as bnb and eth work). With protocol: that protocol's TVL on the chain. Alone: the ch |
limit | integer | — | Rows in a ranking or a breakdown, 1-50 (default 10). |
protocol | object | — | Protocol name or slug, e.g. aave, uniswap-v3, lido (a parent such as aave sums its versions). Omit for a chain or the overview. An unknown name is a 422 with su |

Why get_protocol_tvl is rated Low
Even though get_protocol_tvl only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs get_protocol_tvl safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_protocol_tvl, this is the rule to start with:
get_protocol_tvl is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every get_protocol_tvl call is checked against it from then on.
Questions about get_protocol_tvl
chainpeek: Get protocol or chain TVL with 1d and 7d change. For fees and revenue use get_protocol_fees; for DEX volume use get_dex_volume. Returns the TVL of a protocol or chain with 1d and 7d change, the protocol's chains or the chain's largest protocols, or the largest chains and protocols, from Tanod's cache of DefiLlama data. Input: optional protocol, optional chain and limit; give one, both or neither. Cached DefiLlama data (refreshed every few hours), never live; as_of shows its age; an unknown name is a 422 with suggestions and a missing or over-2-day-old cache a 503 (neither charged). Informational only. Typically under 1 s (a local cache read). Price: USD 0.004. Free: 10 chain reads per IP per UTC day. Docs: https://tanod.dev/learn/defi-data-api.html. It is categorised as a Read tool in the Tanod MCP Server, which means it retrieves data without modifying state.
get_protocol_tvl accepts 3 parameters: chain, limit, protocol. The full parameter table on this page comes from the server's own tool schema.
Register the Tanod MCP server in PolicyLayer and add a rule for get_protocol_tvl: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tanod. Nothing to install.
get_protocol_tvl is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_protocol_tvl rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_protocol_tvl. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_protocol_tvl is provided by the Tanod MCP server (https://tanod.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
