Get the COA account information for a Flow address on flow blockchain, the flow address is 16 characters long or 18 characters long with 0x prefix NOTE: This is a flow blockchin tool, not for flow EVM chain.
AI agents call get_coa_account to retrieve information from Flow MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns blockchain account information (COA = Cadence Owned Account details) for a given Flow address. It has no side effects, does not modify state, and does not execute code or commands. It is a pure data retrieval operation, fitting the 'Read' category with low severity due to limited blast radius if misused (an agent could only retrieve account details, not modify or spend assets).
From the tool's definition Tool name 'get_coa_account' with description stating 'Get the COA account information' — retrieves data about Cadence Owned Accounts without modifying, deleting, or executing operations.

It is categorised as a Read tool in the Flow MCP MCP Server, which means it retrieves data without modifying state.
Register the Flow MCP server in PolicyLayer and add a rule for get_coa_account: 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 Flow MCP. Nothing to install.
get_coa_account 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_coa_account 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_coa_account. 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_coa_account is provided by the Flow MCP server (outblock/flow-mcp-monorepo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
