Side-by-Side Model Context Protocol Comparison
Agy Bridge vs Stellify MCP
In-depth architectural comparison of the Agy Bridge and Stellify MCP 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
Agy Bridge
Coding Agents · Local stdio
Quality: 68/100 (Great) | Auth: other
Stellify MCP
Coding Agents · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
Verdict Summary: Choose Agy Bridge if you need specialized Coding Agents tools running via a local process. Choose Stellify MCP if your workspace requires Coding Agents integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Agy Bridge when:
You need dedicated capabilities in the Coding Agents domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
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.
Build Laravel apps through conversation. Code stored as structured JSON for surgical AI edits.
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.
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).
Agy Bridge is categorized under Coding Agents and uses a local stdio subprocess. In contrast, Stellify MCP belongs to Coding Agents using remote streaming HTTP/SSE transport. Select Agy Bridge when you need capabilities focused on coding agents and Stellify MCP when you require tools for coding agents.
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.
Stellify MCP Tools (32)
get_project
Get the active Stellify project for the authenticated user. **Call this first before any other operations.**
get_directory
Get a directory by UUID to see its contents.
create_directory
Create a new directory for organizing files.
create_file
Create a new file in a Stellify project. This creates an empty file shell - no methods, statements, or template yet.
get_file
Get a file by UUID with all its metadata, methods, and statements.
save_file
Save/update a file with its full configuration. This finalizes the file after `create_file`.
search_files
Search for files in the project by name or type.
create_method
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`.
