A universal API bridge for AI agents
Full API coverage
Every operation in an OpenAPI spec becomes a tool. Not a curated subset—the whole API.
AI-native tools
Upload a spec. AI analyzes every operation and generates tools optimized for reliable execution.
Secure by design
Zero-knowledge encryption protects your credentials. AI calls APIs on your behalf; your secrets stay private.
MCP as a Service
The infrastructure you'd build yourself—but no longer need to.
-
No servers to build or operate
Toolcog runs the infrastructure. Point your MCP client at mcp.toolcog.com and start using APIs with AI.
-
Any OpenAPI spec works
Real-world specs are messy. The execution engine handles protocol complexity and synthesizes interfaces optimized for AI reliability.
-
Latest MCP features
Deferred tool loading and semantic tool search work out of the box. Toolcog tracks the protocol so you don't have to.
-
Uniform security and management
Every API gets the same credential encryption, the same access controls, the same audit logging. No per-integration security decisions.
Take MCP off your plate
Building world class MCP servers requires vector databases, embedding pipelines, credential vaults, and protocol expertise. Toolcog handles it so you can focus on your product.
No tool definitions to write. OpenAPI specs are interpreted at runtime, not compiled into code. Every operation becomes a tool AI can discover and call, without code generation or SDK wrappers.
No infrastructure to build. Semantic search requires vector databases, embedding pipelines, index maintenance. Credential security requires vault architecture. Toolcog provides all of it.
No integrations to maintain. APIs change, specs update, protocols evolve. The infrastructure handles version compatibility, so everything keeps working.
Upload a spec, get an MCP server. Building a world class MCP server requires vector databases, embedding pipelines, and credential encryption. Toolcog handles all of it.
AI fills in the gaps. A frontier model analyzes each operation and generates what specs lack: clear descriptions, human-readable titles, consent classification, and semantic search intent phrases. Your API becomes discoverable even when the original spec was minimal.
The spec stays the source of truth. When your API changes, you update the spec. The AI enrichment runs again automatically—descriptions, titles, intent phrases all regenerate to match.
Internal APIs work like public ones. Upload your internal API specs and they get the same semantic search, credential security, and protocol handling. No special treatment required.
Catalogs scope what agents can access. Create a payments catalog for finance, a DevOps catalog for infrastructure. Different teams get different access boundaries.
Security you can verify. Zero-knowledge credential encryption—we cannot decrypt your secrets. Audit trails track every operation. The security model is the same whether you have ten APIs or ten thousand.
What makes Toolcog different
OpenAPI specs execute directly, without code generation or SDK wrappers. Credentials are protected by zero-knowledge encryption. Semantic search works across hundreds of thousands of operations.
Spec-driven execution
OpenAPI specs are the source of truth. There's no code generation and no SDK wrappers—update your spec and the tools update automatically.
Zero-knowledge credentials
Credentials are protected by four-tier envelope encryption, with keys derived from your session token. Toolcog cannot decrypt them—by design.
AI-powered gap filling
Frontier models analyze each operation and generate what specs lack: clear descriptions, human-readable titles, behavior annotations, and semantic search phrases.
