# Upgrading MCP Connector to Version 1.0.0

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

MCP Connector 0.1.0-BETA is deprecated. Use MCP Connector 1.0.0 instead. MCP Connector 1.0.0 is not
backward-compatible with the 0.1.0-BETA version of this connector.

## Changes in This Release

This release contains the following changes:

- Streamable HTTP Transport

  Support for Streamable HTTP transport is added. This transport method replaces the deprecated SSE
  transport for better scalability and cloud compatibility.

- Custom Response Headers

  Added support for custom headers on all exposed endpoints.

- Enhanced Error Handling

  Improved error handling with specific error types and better error messages.

- Performance Improvements

  Added caching support and timeout configurations.

- Input Validation

  Enhanced parameter validation with JSON schema constraints.

- These new types are added:

  - Call Tool Response

  - Resource Content

  - Resource Metadata

  - Tool Metadata

  - New Session Request

  - Resource Request

  - Text Tool Response Content

  - Text Resource Tool Response Content

  - Blob Resource Tool Response Content

  - Blob Resource

- The `mule.http.service.implementation=NETTY` property is no longer required and must be
  [removed](#remove-property).

- The `<mcp:resource-content>` element under `<mcp:resource-listener>` is renamed to
  `<mcp:resource-listener-content>`. If you used the 0.1.0-BETA version of this connector, you must
  manually rename the element in the connector’s configuration XML.

## Removed Features

- The `<mcp:resource-capabilities>` and `<mcp:tool-capabilities>` configuration attributes are
  removed.

- The `<mcp:add-dynamic-resource>` operation is removed. The MCP server always advertises itself as
  non-dynamic.

## Update the POM File Dependency

If you are using MCP Connector 0.1.0-BETA, you must update your POM file dependency to:

```xml
<dependency>
  <groupId>com.mulesoft.connectors</groupId>
  <artifactId>mule-mcp-connector</artifactId>
  <version>1.0.0</version>
  <classifier>mule-plugin</classifier>
</dependency>
```

Note that the `<groupId>com.mulesoft.connector</groupId>` is changed so that `connector` is now
plural `connectors`.

## Remove the NETTY Property

If you used the 0.1.0-BETA version of MCP Connector and added the
`-Dmule.http.service.implementation=NETTY` property, remove it anywhere you added it, including the:

- `AnypointStudio.ini` file

- Debug configuration

- Apps' properties
