⚠️ Breaking Changes

The Result.Meta field type has changed from map[string]any to *Meta. Code that directly accesses or sets this field will need to be updated:

// Before (v0.36.0 and earlier):
result.Meta = map[string]any{"key": "value"}

// After (v0.37.0):
result.Meta = &mcp.Meta{AdditionalFields: map[string]any{"key": "value"}}

chore(Srv/stdio): duplicated setting of ErrorLogger by @cryo-zd in #306
fix: handle the situation where the channel is closed by @button-chen in #304

Breaking Changes

In v0.29.0, MCP-Go introduces breaking changes to tool request handling. The main change is that request.Params.Arguments is no longer directly accessible as a map. Instead, you must use the new GetArguments() method to retrieve arguments as a map. For type-safe argument access, new helper methods like RequireString(), RequireFloat(), and RequireBool() have been added. To migrate:

Replace direct access to request.Params.Arguments["key"] with request.GetArguments()["key"]
For better type safety, use the new helper methods: request.RequireString("key"), request.RequireFloat("key"), etc.
For complex argument structures, use the new BindArguments() method with a struct, or try the new typed tool handlers with mcp.NewTypedToolHandler() as shown in the new examples/typed_tools example.

This PR was generated by Mend Renovate. View the repository job log.

The build was failing because `request.Params.Arguments` was being indexed without a type assertion, and it was not handling cases where it could be `nil`. This change adds a type assertion to `map[string]interface{}` and a `nil` check to prevent panics, ensuring the MCP handler can gracefully handle requests with missing or invalid arguments.
