UnifAI

Discovers and maintains a dynamic registry of available tools by querying the UnifAI Network, enabling MCP servers to access tools without pre-configuration. The system queries a centralized network index to retrieve tool metadata, schemas, and endpoints, then caches and updates this registry at runtime. This allows tools to be added or removed from the network without requiring server restarts or code changes.

Executes tools discovered from the UnifAI Network by marshaling function calls through standardized JSON schemas and routing to the appropriate provider endpoints. The system validates input parameters against tool schemas, handles authentication per-provider, and manages response serialization back to the calling MCP client. Supports heterogeneous tool implementations (REST APIs, gRPC, native functions) through a unified invocation interface.

Implements the Model Context Protocol (MCP) server interface to expose UnifAI Network tools as MCP resources and tools, enabling any MCP-compatible client (Claude, LangChain, custom agents) to discover and invoke network tools. The server translates between MCP's resource/tool model and UnifAI's tool registry, handling MCP message serialization, request routing, and response formatting according to the MCP specification.

Searches the UnifAI Network tool registry using semantic queries and capability filters to find relevant tools for a given task. The system accepts natural language descriptions or structured capability requirements, queries the network index (likely using embeddings or keyword matching), and returns ranked results with relevance scores. Filters can be applied by category, provider, required permissions, or execution constraints.

Manages execution context for tool calls including parameter binding, state tracking across multi-step tool chains, and result caching. The system maintains execution state (current tool, parameters, intermediate results) and provides context to subsequent tool calls, enabling sequential tool composition. Implements optional result caching to avoid redundant tool invocations with identical parameters.

Manages authentication credentials for tools from different providers, supporting multiple auth schemes (API keys, OAuth 2.0, mTLS, custom headers). The system stores credentials securely (encrypted at rest), handles token refresh for OAuth flows, and injects appropriate credentials into tool invocation requests. Supports per-user credentials and per-tool credential overrides.

Handles tool execution errors with provider-specific error parsing, fallback strategies, and graceful degradation. The system catches tool invocation failures, parses provider-specific error responses, attempts retries with exponential backoff, and can fall back to alternative tools or cached results. Provides detailed error context to agents for decision-making.

Tracks tool invocation metrics (latency, success rate, error rate, cost) and provides analytics dashboards or exportable reports. The system logs each tool call with parameters, results, execution time, and provider information, enabling usage analysis and cost tracking. Supports filtering by tool, provider, user, or time range.

Enables definition of reusable tool workflows as templates that compose multiple tools with conditional logic, loops, and data transformations. Templates are defined declaratively (likely in YAML or JSON) and executed by the MCP server, handling parameter passing between tools and managing execution flow. Supports variable substitution, conditional branches, and error handling within workflows.
