Overview

Stacklink connects tools, knowledge, accounts, events, and workbenches for AI agents. It is the backend boundary for external provider integrations and verified knowledge packs, so your app keeps only its own product reasoning and user experience.

The boundary

Stacklink owns external provider accounts, provider toolkits, tool search, tool execution, knowledge packs, verified evidence receipts, triggers, polling, webhooks, jobs, artifacts, and raw provider events. Your consumer app owns final answer generation, product policy, and product-specific UI. Stacklink returns results, artifacts, events, and verified evidence — you decide how to present or act on them.

What you get

One session contract

A single session scopes an end-user's tools, connected accounts, and knowledge packs. No per-provider bridge tools.

Agentic tool discovery

Search hundreds of provider tools by intent, fetch exact schemas, then execute — through a small set of meta-tools or over MCP.

Verified knowledge

Citation-backed compliance knowledge with evidence receipts, currentness, and deterministic structured calculations.

Connections & auth

A hosted connect flow for end-users to link provider accounts. Credentials are encrypted and never reach the model.

Triggers & events

Subscribe to provider events via webhook or polling and receive signed, normalized event deliveries.

Remote workbench

A sandboxed runtime where agents run code and bash with provider tools, LLM, and web-search helpers.

The subsystems

Subsystem	What it does
Sessions	Scope tools, accounts, knowledge, and the MCP surface for one tenant/user.
Toolkits & tools	~11 providers, 400+ model-callable tools, discovered by semantic search.
Connections & auth	Auth configs (your OAuth app) and connected accounts (the end-user's account).
Knowledge packs	Versioned, evidence-backed legal/compliance corpora with structured rule modules.
Triggers & webhooks	Provider events in (webhook/polling) and signed events out to your app.
Workbench	A secure sandbox where agents run code and bash with provider, LLM, and web helpers.
Observability	`platform_request_logs` and `tool_execution_logs` for every call.
