get contract by symbol
AI agents call get_contract to retrieve information from BaseQL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches contract information from the Base blockchain using a symbol lookup. It is a simple data retrieval operation with no side effects, no code execution, and no ability to modify, delete, or move assets. The worst-case misuse is retrieving incorrect contract information, which has low blast radius.
From the tool's definition Tool retrieves contract details 'by symbol' with no modification capability. Server description emphasizes 'query' and 'access to' blockchain data for 'analytics', indicating read-only operations.
Attacks that exploit this kind of access
get contract by symbol. It is categorised as a Read tool in the BaseQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the BaseQL MCP Server MCP server in PolicyLayer and add a rule for get_contract: 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 BaseQL MCP Server. Nothing to install.
get_contract 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_contract 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_contract. 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_contract is provided by the BaseQL MCP Server MCP server (jnix2007/baseql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
