What add_contact_tag does on instantKOM MCP Server
AI agents use add_contact_tag to create or update resources in instantKOM MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your instantKOM MCP Server environment.
Why add_contact_tag is rated Medium
This tool creates or modifies contact metadata (tags) without permanent destruction or irreversible consequences. Tags can typically be removed, making this a reversible Write operation rather than Destructive. The blast radius is low—adding a tag does not expose sensitive data, execute code, move money, or delete information. Low severity reflects the minor nature of metadata modification on a single contact.
From the tool's definition Tool name 'add_contact_tag' and description 'Add a tag to a specific contact' indicate a data modification operation. Tags are metadata that can be added to and removed from contacts reversibly.
Attacks that exploit this kind of access
The rule that runs add_contact_tag safely

add_contact_tag stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect instantKOM MCP Server, apply this rule, and every add_contact_tag call is checked against it from then on.
