MCP REST API
Generic MCP REST API server enabling AI agents to make HTTP requests to any REST API — performing GET, POST, PUT, DELETE and other HTTP methods against arbitrary endpoints, handling authentication headers, and integrating any HTTP REST service into agent-driven workflows without requiring a dedicated MCP server for each service.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS supported. Auth headers stored as env vars. No OAuth. Community MCP. Generic access — limit to necessary APIs.
⚡ Reliability
Best When
An agent needs to call a REST API that doesn't have a dedicated MCP server — the generic HTTP client approach bridges the gap for custom internal APIs.
Avoid When
The target API has a dedicated MCP server (use that instead for better tool definitions), or you need advanced auth flows like OAuth.
Use Cases
- • Calling custom internal REST APIs that don't have dedicated MCP servers
- • Prototyping API integrations before building dedicated MCP servers
- • Testing REST API endpoints from development and QA agents
- • Integrating legacy REST services into agent workflows
- • Building generic HTTP orchestration from workflow agents
- • Accessing APIs with simple authentication from data retrieval agents
Not For
- • Production use with sensitive APIs (generic tool with limited auth security)
- • GraphQL or gRPC APIs (REST-only tool)
- • High-volume API calls requiring rate limit management per-service
Interface
Authentication
Configurable auth headers per request. Supports static API keys, bearer tokens, and basic auth. No OAuth flow support. Configure auth in environment or per-request.
Pricing
Free open source MCP. Target API costs depend on provider.
Agent Metadata
Known Gotchas
- ⚠ Generic tool — agents must know target API schema without MCP-level tool definitions
- ⚠ No OAuth flow support — only static credentials/tokens
- ⚠ Rate limit handling must be implemented at agent level — tool doesn't throttle
- ⚠ Error responses from target API passed through — agents must interpret per-API error formats
- ⚠ Request/response format awareness required — agents must understand target API contract
- ⚠ Community MCP — validation against each target API must be done separately
