Commonly used to get a list of all the token holders for a specified ERC20 or ERC721 token. Returns historic token holders when block-height is set (defaults to latest). Useful for building pie charts of token holders.
AI agents call getTokenHolders to retrieve information from Somnia MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a data retrieval operation that queries blockchain state without side effects. It reads historical or current token holder information for analysis purposes (e.g., building pie charts). There is no capability to modify balances, execute transactions, delete data, or move funds. The tool's function is purely informational.
From the tool's definition Tool retrieves a list of token holders for ERC20/ERC721 tokens with optional historic data; described as 'Commonly used to get a list' with no mention of modifying, executing, deleting, or moving assets. Returns query results only.

Commonly used to get a list of all the token holders for a specified ERC20 or ERC721 token. Returns historic token holders when block-height is set (defaults to latest). Useful for building pie charts of token holders. It is categorised as a Read tool in the Somnia MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Somnia MCP Server MCP server in PolicyLayer and add a rule for getTokenHolders: 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 Somnia MCP Server. Nothing to install.
getTokenHolders 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 getTokenHolders 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 getTokenHolders. 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.
getTokenHolders is provided by the Somnia MCP Server MCP server (vastavikadi/somnia-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
