Overview

Every Logic MCP connection provides a set of built-in tools that let a connected AI client discover, run, inspect, and even build your Logic agents on your behalf — without switching back to the Logic dashboard. Your agents aren’t exposed as individual client tools. Instead, a client reaches them through these built-in tools — for example, Logic: List Agents to find an agent and Logic: Call Agent to run it. In your client, the built-in tools appear at the top of the list with a Logic: prefix (for example, Logic: List Agents). Under the hood each has a raw tool ID — some clients and logs show that instead — so the entries below pair the display name with its ID. What a client can do depends on the permission you give the MCP server when you create or edit it:
PermissionWhat a client can do
Execute onlyDiscover, run, and inspect existing agents
AuthorEverything above, plus create and edit agents
Creating and editing agents is only available on servers set to Author permission. A server set to Execute only can read and run your agents but can’t change them — Logic enforces this on the server, no matter what the client requests.

​
Read & execute

Available on every connection:
  • List agents (_logic_list_agents) — see all your agents, including drafts. This is how a client discovers what’s available to run; newly created or edited agents show up here immediately.
  • Read an agent (_logic_read_agent) — view its spec, the input it expects, and every way it can be triggered (email address, REST endpoint, MCP server, and schedules).
  • View executions (_logic_view_executions) — review recent runs and their results to see what succeeded or failed, and why.
  • Call an agent (_logic_call_agent) — run any agent by name. Since agents aren’t exposed as individual tools, this is how a client executes them. Runs are asynchronous, so the client polls Check execution status (_logic_check_execution_status) until the result is ready — see Asynchronous Task Execution.
Runs are asynchronous, so a result isn’t always instant — the assistant checks back on its own (by polling _logic_check_execution_status) until the run finishes, which can take a few minutes for longer workflows. An Execute only server sees only the runs it started; an Author server sees all of an agent’s runs.

​
Authoring

Available on servers set to Author permission:
  • Create an agent (_logic_create_agent) — turn a title and a spec into a new agent.
  • Edit an agent (_logic_patch_agent) — update an existing agent’s spec with targeted find-and-replace edits, and optionally rename it.
New and edited agents are saved as a draft by default. The client can publish in the same step to make the agent live and callable right away; otherwise your published version keeps running unchanged until you choose to publish.
When the assistant creates or publishes an agent, it’s available right away — it shows up in Logic: List Agents immediately and can be run with Logic: Call Agent, with no need to reconnect or restart the client.
