Curated default MCP tools

The default Sourcegraph MCP endpoint now prioritizes the most commonly used context-gathering tools, while /.api/mcp/all exposes the full tool suite.

As previously announced, the default Sourcegraph MCP endpoint at /.api/mcp now exposes a smaller, more focused set of tools for common context-gathering workflows.

This reduces tool-list noise for MCP clients and avoids spending context window budget on lower-frequency tools that most agents do not need by default.

By default, /.api/mcp now exposes the following tools:

read_file
list_files
keyword_search
nls_search
list_repos
commit_search
diff_search
deepsearch_read

If you want the full Sourcegraph MCP tool suite, including Deep Search and code navigation tools like go to definition and find references, use /.api/mcp/all. The focused /.api/mcp/deepsearch endpoint remains available for Deep Search-only workflows, and the deprecated /.api/mcp/v1 endpoint still exposes the full suite with the legacy sg_-prefixed tool names for backward compatibility.
