The difference

With Fridayy vs. Without Fridayy

Same backend. Two very different weeks.

Development Time

< 60 seconds. Automatic discovery generates standard tools instantly.

Codebase Impact

Zero code rewriting. Reads OpenAPI specs or existing routes non-invasively.

Destructive Security

3-Tier Risk Engine. Destructive endpoints default to BLOCKED until human review.

Secret Management

Zero-Leak Isolation. Secrets load exclusively via runtime FRIDAYY_* env variables.

Schema Compatibility

Automated Normalization. Translates everything into strict JSON Schema Draft-7.

AI Autonomous Setup

Point-and-Play (point/). Point AI to point/AI_INSTRUCTIONS.md for auto-setup.

Under the hood

A five-stage pipeline

From raw routes to an approved, audited MCP server.

STAGE 01•SCANNING AST & SPECS
$ pipeline:Discovered 18 endpoints across REST routes & OpenAPI definitions.

Capabilities

Everything the bridge needs

Discovery, security, transport and observability — batteries included.

01 / Discovery

Automated Capability Discovery

Scans OpenAPI specs (openapi.yaml, swagger.json) or parses AST route trees in Express, Fastify and Koa projects to find every endpoint automatically.

OpenAPI 3.1Swagger 2.0ExpressFastifyKoa
Risk engine

3-Tier Zero-Trust Classification

Every detected tool is classified before an AI can touch it.

  • READGET /productsPre-approved
  • WRITEPOST /ordersPending check
  • DESTRUCTIVEDELETE /accountBlocked

{ "tool": "delete_account", "status": "BLOCKED" }

02

Zero-Leak Secret Isolation

Never put API keys or Bearer tokens in LLM prompts. Credentials resolve at execution time from FRIDAYY_API_KEY and FRIDAYY_BEARER_TOKEN.

03

Autonomous AI Guidance (@point/)

Drop Fridayy into any codebase. Reference @point/AI_INSTRUCTIONS.md and Cursor or Claude configures and runs the whole MCP pipeline itself.

04

Dual Transport MCP Engine

Stdio for local clients like Claude Desktop and Cursor IDE. SSE over HTTP for remote agents, background workers and webhooks.

05

Rate Limiting & Tamper-Evident Audit Log

Sliding-window rate limiters prevent API exhaustion, while JSONL audit logging records every tool call, caller identity and sanitized response.

CLI workflow

Five commands to a live MCP server

Human-in-the-loop by design — nothing ships to an AI without your approval.

Initialize

Creates fridayy.config.json with detected API sources and environments.

bash
npx fridayy init

AI client setup

Connect your assistant

Copy a config, restart the client, and your API is a tool.

AI Quick-Point

Let the agent set itself up

Point Cursor or Claude at the instructions file in the repo and it will scan, generate, review and test your MCP server autonomously.
