At a Glance & Executive Verdict
Stellify MCP
Coding Agents · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
Agy Bridge
Coding Agents · Local stdio
Quality: 68/100 (Great) | Auth: other
Verdict Summary: Choose Stellify MCP if you need specialized Coding Agents tools running via a hosted cloud SSE transport. Choose Agy Bridge if your workspace requires Coding Agents integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Stellify MCP when:
You need dedicated capabilities in the Coding Agents domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Build Laravel apps through conversation. Code stored as structured JSON for surgical AI edits.
Delegate heavy tasks from Claude Code (or any MCP client) to the Antigravity CLI (Gemini): file analysis, repo archaeology, web lookups, and adversarial second-opinion code reviews. Quota-aware model failover with cooldowns, per-tool timeouts, and multi-turn session continuity.
Stellify MCP is categorized under Coding Agents and uses a remote streaming HTTP/SSE transport. In contrast, Agy Bridge belongs to Coding Agents using local stdio subprocess. Select Stellify MCP when you need capabilities focused on coding agents and Agy Bridge when you require tools for coding agents.
Create a method signature in a file (without implementation).
add_method_body
Parse and add code to a method body. Stellify parses the code into structured JSON statements.
search_methods
Search for methods in the project by name or within a specific file.
create_statement
Create an empty statement in a file. This is step 1 of 2 - you must call `add_statement_code` next.
add_statement_code
Add code to an existing statement. This is step 2 of 2 - call after `create_statement`.

analyze_files
Delegate file analysis to the Antigravity CLI (Gemini) instead of reading files yourself. USE THIS whenever a file is large (>200 lines) or the task spans more than 3 files: logs, database dumps, generated code, cross-file reviews, comparisons. The files never enter your context — only the answer does.
deep_search
Delegate codebase archaeology to the Antigravity CLI: git log/diff/blame spelunking, wide greps across a repo, 'when/why did X change', 'where is Y used'. USE THIS instead of running many search commands yourself — it saves your context.
web_lookup
Delegate a web/documentation lookup to the Antigravity CLI (Gemini with web access): library docs, API references, error messages, current versions, external knowledge. USE THIS when you need information you don't have or that may be newer than your training data.
adversarial_review
Get an adversarial second opinion from a different model family (Gemini Pro). ALWAYS use this for plan critiques, design reviews, and pre-merge code review: it hunts for flaws, edge cases, security issues, and unstated assumptions you may have missed.
follow_up
Continue a previous Antigravity session by session_id (returned by every other tool). USE THIS for follow-up questions about a prior delegation — the full prior context is already on agy's side, so you don't resend anything.
delegate
Raw delegation to the Antigravity CLI for heavy tasks that don't fit the other tools. agy has full tool access (shell, file reads, web) in the given cwd.
