Public predicates

.. index:: start/2 .. _mcp_server/0::start/2:

start/2 ^^^^^^^^^^^

Starts the MCP server with default options.

| Compilation flags: | static

| Template: | start(Name,Application) | Mode and number of proofs: | start(+atom,+object_identifier) - one

---

.. index:: start/3 .. _mcp_server/0::start/3:

start/3 ^^^^^^^^^^^

start/5 ^^^^^^^^^^^

Starts with custom streams and options.

| Compilation flags: | static

| Template: | start(Name,Application,Input,Output,Options) | Mode and number of proofs: | start(+atom,+object_identifier,+stream,+stream,+list) - one_or_error

---

.. index:: notify/1 .. _mcp_server/0::notify/1:

notify/1 ^^^^^^^^^^^^

Publishes an application event to the active adapter.
