Internal MCP Crate Cleanup #4800

alexhancock · 2025-09-24T22:05:03Z

Fully gets rid of mcp-client and mcp-core making all our mcp tooling just use the rust-sdk
Removes concept of ToolCall and replaces it with the similar CallToolRequestParam from rmcp
Associated required code changes, compilation fixes etc

alexhancock · 2025-09-26T01:47:52Z

@jamadeo how do you feel about the fact that this removes mcp-client but still impl McpClientTrait for McpClients

Do you think we should unwind that in a change where we remove those crates, or ok to do in a followup?

Also I realize this is a big PR so can sync on it when I've verified it's ready for review otherwise.

really nice. I left some nitpick comments, mostly places where I think there are unnecessary clones (.to_string().clone()) and some places where there's another level of if-nesting that could be replaced with a .and_then(..)

But feel free to merge before addressing all of them, wouldn't want to be constantly fixing conflicts.

Maybe the one thing to give an extra look to is the 1 that became None in acp.rs

-                            meta: None,
-                        });
+                    if let Some(args_map) = args {
+                        if let Some(path_str) = args_map.get("path").and_then(|p| p.as_str()) {


nit: could be a single if let Some(.. with a .and_then

+                            if path.exists() && path.is_file() {
+                                locs.push(acp::ToolCallLocation {
+                                    path: path_str.into(),
+                                    line: None,


this is line: Some(1) on the left but None here, is that deliberate?

+                                                        tool_name: tool_call
+                                                            .name
+                                                            .to_string()
+                                                            .clone(),


I don't think you need to .clone() here since .to_string() should return an owned value

match call.name.as_ref()

+                                            .unwrap_or_else(|| "tool".to_string().into());


did you mean to change this from "unknown" to "tool"?

good catch - thank you

-                                        style(format!("{}", item)).green()
-                                    );
+    if let Some(args) = &call.arguments {
+        if let Some(Value::Array(task_parameters)) = args.get("task_parameters") {


could chain these two as well

crates/goose/src/providers/formats/snowflake.rs

-            let tool_call = ToolCall::new(name, Value::Object(serde_json::Map::new()));
-            message = message.with_tool_request(id, Ok(tool_call));
+    if let Some(id) = tool_use_id {
+        if let Some(name) = tool_name {


could chain these to remove a nesting level

Also I realize this is a big PR so can sync on it when I've verified it's ready for review otherwise.

I think that's fine, if there's some point in the future where it makes sense to remove a layer of abstraction, we can always do that.
