MCP Bridge — Connect any API to any AI agent
AppFactor
Auto-generate MCP tool definitions from REST, GraphQL, SOAP, or gRPC APIs to connect any API to any AI agent, self-hosted and production-ready.
Key features
- Schema Import: Supports OpenAPI (JSON/YAML), GraphQL introspection, WSDL (SOAP) and gRPC (server reflection or .proto files) via URL, paste, or file upload to onboard APIs without code changes.
- Auto-generated MCP Tools: Converts each API operation into a fully typed MCP tool with input/output schemas, parameter mappings, descriptive documentation, and behavioural annotations for accurate agent discovery and invocation.
- Runtime Validation & Mapping: Validates inputs against generated schemas, maps parameters and authentication details, and forwards requests to backend services while preventing malformed calls.
- Response Post-processing: Normalizes and trims API responses to reduce token consumption and produce agent-friendly outputs, improving cost-efficiency and relevance when used by LLMs.
- Authentication & Governance: Centralizes handling of API authentication, rate limiting, and access controls so agents call services securely without shipping credentials or custom glue code.
- High-performance Rust Core: Built in Rust for memory safety and high throughput to support production-scale deployments with minimal runtime dependencies.
- Deployability & Marketplaces: Self-hosted in minutes with availability via AWS Marketplace and Microsoft Azure Marketplace, enabling enterprise deployment patterns and marketplace procurement.
- Code Mode & Extensibility: Provides a code/configuration mode for advanced customizations and scaling, allowing platform teams to extend mappings, annotations, and post-processing logic.
- Auto-generate MCP tool definitions from API schemas (OpenAPI JSON/YAML, GraphQL introspection, WSDL, gRPC server reflection/.proto)
- Schema import via URL, paste, or file upload
- Typed input/output schemas, parameter mappings and behavioral annotations per operation
- Runtime validation and parameter mapping before forwarding requests to backend APIs
- Authentication configuration and secrets management for upstream APIs
- Response post-processing to reduce token usage and enforce tool boundaries
- Self-hosted deployment with zero external SaaS dependencies at runtime
- Built in Rust for memory-safety and high throughput
- Integration-ready via AWS Marketplace and Microsoft Azure Marketplace
- Observability, rate limiting and governance features for enterprise deployments
Best for
- Expose Internal Services to Agents: Platform engineering teams publish internal microservice endpoints as discoverable MCP tools so LLM-based assistants can perform tasks without bespoke adapters.
- Secure Enterprise Agent Integrations: Enterprises self-host MCP Bridge to avoid sending credentials to third-party services while enforcing RBAC, rate limits, and auditability for agent-driven actions.
- Legacy API Modernization for Agents: Wrap legacy SOAP/WSDL or gRPC services as MCP tools so modern AI agents (Claude, ChatGPT, Gemini, Copilot-style clients) can call them without API rewrites.
- AI-driven Customer Workflows: Enable AI assistants to query and act on systems like billing, CRM, or support platforms by auto-generating tools from existing OpenAPI specs and enforcing auth and schemas.
- Third-party Service Orchestration: Rapidly onboard SaaS APIs (Stripe, Zendesk, e-commerce platforms) to agent workflows by importing schemas and exposing governed tools through a single control plane.
- Observability and Safe Execution: Provide observability, input validation, and response post-processing to reduce erroneous agent calls and token usage in production agent workflows.
- Expose internal REST/GraphQL/SOAP/gRPC endpoints to LLM-based agents without rewriting services
- Provide a managed tool layer for AI engineers to build agents that call enterprise APIs securely
- Standardize API-to-agent access across an organization (RBAC, auth, auditability)
- Quickly enable third-party SaaS integrations for assistants by importing existing specs
- Run on-prem or in cloud marketplaces to satisfy data residency and compliance requirements
QApilot MCP for Android
QApilot
MCP server that lets Claude, Cursor or Codex drive real Android devices and emulators to record and replay app tests in plain English.
Key features
- Plain-English Android Automation: Describe a test flow conversationally and the MCP server plans and executes each step on a connected device or emulator, with no Appium code written by hand.
- MCP Client Integration: Ships config blocks for Claude Desktop, Cursor and OpenAI Codex so the server appears in the client's connected tools after a restart.
- Local Device and Emulator Control: Runs against USB-debugging devices or AVD emulators through a locally started Appium server with pinned Appium 2.19.0 and UiAutomator2 4.2.6 versions.
- Live Browser Preview: Every app-launch call returns a preview URL so the device screen can be watched in a browser while the test executes.
- Readable Step Recording: Step titles are generated automatically and capped at 50 characters with no XPath, keeping reports and the dashboard legible.
- Test Case Persistence: After a passing run, only the happy-path steps are accepted and pushed into a named QApilot project test case for future replay.
- Batch and Spreadsheet Execution: Saved test cases can be replayed one at a time, as a batch of IDs, or driven from an Excel sheet.
- Conversational Account Setup: Registration, activation email and login can all be triggered through prompts, or automated with credentials supplied in the client config env block.
Best for
- Regression Suites Without Code: QA engineers build and replay Android regression flows by describing them, avoiding an Appium codebase to maintain.
- Pre-Launch Sanity Testing: A team automates a full sanity suite for an app ahead of launch and reruns it before each build instead of doing multi-day manual passes.
- OTP and Login-Gated Flows: Testers record store-owner or user journeys that pass through OTP and authentication screens that block conventional scripted automation.
- Exploratory Testing from an IDE: Developers in Cursor or Codex drive a connected emulator to reproduce a bug while staying in their editor.
- Form and Filter Validation: Testers verify multi-field enquiry forms, filter selections and comparison screens with assertions expressed as sentences.
- Demo and Review Sessions: Teams share the live preview link so stakeholders can watch a test run against a real device as it executes.
