Model Context Protocol (MCP) Server & CI/CD Gate

System prompts are just suggestions. Resonant enforces checks in code before your AI saves.

When an AI coding assistant works across a multi-file repository, written rules in a prompt eventually get ignored: the AI changes a function in File A and breaks a caller in File B, follows an outdated design note after the code has changed, or claims “all tests pass” without running them.

Resonant (`resonant-exocortex`) is an MCP server for Antigravity, Cursor, and Claude Code—linked to a Cloud CI/CD Pull-Request Gate—that checks edits in milliseconds before saving and binds project memory directly to your code.

01 • resonant_verify_cegar

Pre-Save Behavioral & Security Check

Before your AI writes a file to disk, Resonant inspects the modified function, tests boundary inputs in memory (such as empty lists [] or 0), compares old vs. new behavior, and checks for leaked secrets or in-place caller list mutations.

02 • resonant_memory_jtms

Memory That Expires When Code Changes

Every architectural note stored in Resonant’s SQLite database is linked to the SHA-256 fingerprint of the actual code function. The moment you edit that function later, outdated notes about it expire automatically—and fixed bug patterns become local 0-token rules.

03 • resonant_architect_orient & ci_gate

Surgical Slicing & Cloud CI/CD Gate

Extracts only the target function, its callers, and Git co-change partners during coding, and links directly to resonant_ci_gate (POST /api/mcp/ci-gate) so Pull Requests are checked against the same learned guardrails before merge.

Connect the Live Resonant MCP Server in Your Editor (Under 30 Seconds)

You don’t need to install Python packages or upload your repository. Connect Claude Code, Cursor, Google Antigravity, or Windsurf directly to our live Python verification engine (https://resonantexo.com/api/mcp — 50 free calls/day per IP in an isolated sandbox, or 5,000 calls/day with a Pilot Key):

Option A • 1-Line Terminal Install for Claude Code

claude mcp add --transport http resonant-exocortex https://resonantexo.com/api/mcp

Option B • mcp_config.json for Antigravity, Cursor & Windsurf

{
  "mcpServers": {
    "resonant-exocortex": {
      "url": "https://resonantexo.com/api/mcp"
    }
  }
}

3 Prompts to Try Right After Connecting

Test 1 • Pre-Save Bug & Bytecode Check

“Refactor this function and pass both old_code and code to resonant_verify_cegar before saving to check for boundary bugs, silent None returns, or dropped guards.”

Test 2 • Multi-File Contract Slicing

“Pass these two files in files to resonant_architect_orient and show me the extracted function contracts, AST hashes, and coupled callers.”

Test 3 • Code-Linked Memory Drift

“Use resonant_memory_jtms to commit an architectural rule linked to this function, then modify the function and run reconcile to see it flag STALE_AST_DRIFT.”
