In-depth architectural comparison of the Code Index and Health Data (your own Supabase) 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
Code Index
Databases · Local stdio
Quality: 63/100 (Good) | Auth: No auth required
Health Data (your own Supabase)
Databases · Local stdio
Quality: 53/100 (Good) | Auth: No auth required
Verdict Summary: Choose Code Index if you need specialized Databases tools running via a local process. Choose Health Data (your own Supabase) 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 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).
Full-text search across functions (name, docstring, body)
search_class
Full-text search across classes
get_function
Get function by exact name (case-insensitive fallback; **(v0.44.0)** on 0 matches returns `did_you_mean` with similar names)
get_class
Get class by exact name (case-insensitive fallback; **(v0.44.0)** on 0 matches returns `did_you_mean` with similar names)
get_object_structure
Structure of a 1C object. **v0.63.0:** object templates are now in the registry — a row `Catalog.X.Template.Y` with the owner, the template kind and a `content_indexed` flag (large templates stay out of the index, yet the template itself is visible and findable by name)
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Code Index is categorized under Databases and uses a local stdio subprocess. In contrast, Health Data (your own Supabase) belongs to Databases using local stdio subprocess. Select Code Index when you need capabilities focused on databases and Health Data (your own Supabase) when you require tools for databases.
Who calls this function? **(v0.35.0)** each row carries the caller's source `path` (distinguishes same-named callers from different files). **v0.62.0:** for 1C configurations, form event handler bindings (`kind: form_binding`) are added to the code callers — such a procedure is run by the platform…
get_callees
What does this function call? **(v0.35.0)** each row carries the source `path
find_path
(v0.23.0)** Shortest path in the call graph between two functions `from`→`to` (iterative cycle-safe BFS over unique `calls` nodes, `max_depth=5`, any language). Returns path edges `[{caller, callee, line}]`. **v0.57.0:** an empty answer carries walk cut-off flags `walk_depth_exhausted` / `walk_node…
get_call_tree
(v0.23.0)** Call tree from a `root` function up to `max_depth` (default 3). `direction`: `callees`/`down` (downstream) or `callers`/`up`. Flat edge list `[{caller, callee, line, depth, path}]` (**(v0.35.0)** `path` = source file of each edge) + nested `{name, children}` tree; `max_nodes` cap
