Agent Lsp vs Code Index
In-depth architectural comparison of the Agent Lsp and Code Index MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Agent Lsp
Databases · Local stdio
Quality: 67/100 (Great) | Auth: No auth required
Code Index
Databases · Local stdio
Quality: 63/100 (Good) | Auth: No auth required
Verdict Summary: Choose Agent Lsp if you need specialized Databases tools running via a local process. Choose Code Index if your workspace requires Databases integration with local subprocess execution. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?
Choose Agent Lsp when:
- You need dedicated capabilities in the Databases domain.

- Your security boundary fits: No auth required (Free / Open Source).
- You have access to required keys:
AGENT_LSP_OUTPUT_FORMAT. - Primary tools included: activate_skill, add_workspace_folder, apply_edit.
Choose Code Index when:
- You need dedicated capabilities in the Databases domain.
- You prefer local stdio subprocess transport architecture.
- Your security boundary fits: No auth required (Free / Open Source).
- Primary tools included: search_function, search_class, get_function.
Feature & Specification Comparison
Tools & Capabilities Breakdown
Agent Lsp Tools (65)
activate_skill
Activate phase enforcement for a skill workflow. Once active, tool calls are checked against the skill's phase permissions. Phases advance automatically as you call tools from later phases. Use this at the start of a skill workflow to enable safety guardrails that prevent out-of-order operations (e.g., applying edits before completing blast-radius analysis).
add_workspace_folder
Add a directory to the LSP workspace, enabling cross-repo references, definitions, and diagnostics. Useful when working across a library and its consumers — after adding the consumer repo, find_references on a library function returns call sites in both repos. Requires start_lsp to have been called first. Language servers that support multi-root workspaces (gopls, rust-analyzer, typescript-language-server) will re-index the new folder automatically.
apply_edit
Apply an edit to a file. Two modes: (1) WorkspaceEdit mode: pass workspace_edit with positional changes returned by rename_symbol or format_document; (2) Text-match mode: pass file_path + old_text + new_text to find and replace text. For full function/method body replacements, consider replace_symbol_body which resolves by symbol name instead of text matching. Always call preview_edit first to verify the edit is safe.
