Get the metadata URI for an ERC1155 token.
AI agents call get_erc1155_token_uri to retrieve information from SEI MCP Server V2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata URIs from ERC1155 tokens on the Sei blockchain. It performs a read-only query operation with no side effects, no data modification, no code execution, and no financial implications. The action is purely informational—fetching a URI pointer to token metadata. This is a classic Read operation with minimal risk of misuse by an AI agent.
From the tool's definition Tool name 'get_erc1155_token_uri' and description 'Get the metadata URI for an ERC1155 token' indicate a retrieval operation that queries token metadata without modifying state.

Get the metadata URI for an ERC1155 token. It is categorised as a Read tool in the SEI MCP Server V2 MCP Server, which means it retrieves data without modifying state.
Register the SEI MCP Server V2 MCP server in PolicyLayer and add a rule for get_erc1155_token_uri: 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 SEI MCP Server V2. Nothing to install.
get_erc1155_token_uri 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_erc1155_token_uri 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_erc1155_token_uri. 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_erc1155_token_uri is provided by the SEI MCP Server V2 MCP server (testinguser1111111/sei-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
