Problem Statement

If I have three dbs (local, staging, prod) and I configure an MCP toolbox for Databases per each, it loads tool descriptions for each. Thankfully, mcp tools of this mcp are relatively light on context space. There are others that are not so much.

Proposed Solution

It would be good if claude recognized mcp tools from same mcp but per different instance and reuse/inherit descriptions.

Alternative Solutions

No response

Priority

Medium - Would be very helpful

Feature Category

MCP server integration

Use Case Example

Have local, staging and production database access each via MCP tools for databases.
