Composio vs Paragon (2026)

Each session gives an agent tools from more than 1,500 toolkits, scoped to one of the customer's users, and Composio manages the OAuth redirects, token exchange and refresh behind them. The agent can pause in the middle of a chat, send the user a Connect Link and retry the tool once the account is connected, and the connection persists for later sessions.

Tools run on the server with the credential injected, never handed to the model. Tool search finds the right tools for a task, custom tools and MCP servers sit alongside the catalog, and Instant tools let an agent call paid third party services such as search and enrichment from a Composio balance without the user opening provider accounts.

ActionKit is one API and MCP server giving an agent hundreds of integration actions across Paragon's connectors, with a uniform interface, agent optimized action schemas and real time execution. The Connect Portal handles OAuth and API key authorization per end user, so each action runs as that user and agents take authenticated action in the user's own SaaS tools.

The sandbox is a persistent Python environment where the agent writes code that calls tools programmatically, with helpers for tool execution, LLM calls, file uploads, direct API calls and web search, error correction on generated code, and state that persists across calls, and a MULTI_EXECUTE meta tool runs several tool calls together. There is no workflow definition, versioned flow, or sequencing and branching that combine deterministic workflow nodes with autonomous agent steps.

Workflows is Paragon's embedded iPaaS for event driven automations, with integration logic authored in TypeScript or a low code editor. A workflow can start from the customer's app, third party webhooks, an integration enabled event, a scheduler or another workflow, and API resources supply reusable triggers and steps. Steps are sequenced, branched and routed deterministically, executions can be reviewed step by step in Monitoring, and CI/CD and Git repo sync are supported.

Triggers react to events in connected apps and deliver them to the customer's webhook as structured payloads. A trigger can be activated for a user, events arrive through an SDK subscription or in production, and trigger instances can be listed, enabled, disabled and deleted. A worked example runs an agent when an email arrives.

Third party events are forwarded to the customer's agent so it can work in the background and respond to what happens in a user's tools. One API subscribes to any user integration event, with normalized webhook policies across integrations. Workflows can be started by app events, integration webhooks, an API resource webhook or a scheduler, so work begins without a person asking.

There is no retrieval structure Composio maintains over the customer's own documents. Its search finds the right tools for a task, and its sandbox can extract text from files an agent is working on.

Managed Sync runs fully managed ingestion pipelines over each end user's third-party sources (files, CRM records, tickets, accounting data). It has automatic backfill, incremental sync, failure recovery and normalized schemas, and scales to hundreds of millions of records. A Permissions API enforces the source system's access control on the ingested data for RAG, and records and file content can then be queried through the Sync API. The synced store persists, scales past any context window and stays queryable.

A Composio session scopes execution state for the run, covering logs, tool memory, MCP state and sandbox files, with sandbox variables and runtime state persisting across calls and cleared after roughly 12 hours of inactivity, and sessions can be reused, updated and deleted. The scope (the session and its user) and the lifetime are stated. This is state carried through one task, and there is no memory layer the agent draws on across runs.

Sourcedocs.composio.dev/docs/security/data-retentionread 2026-10-24

Each connected user's authorization and synced third party records persist. Managed Sync, ActionKit and Workflows have no memory layer that keeps an agent's state or a user's context across runs. The synced data store holds records, not agent memory with a set scope or lifetime.

A session can require the user's approval before chosen tools run. The customer picks them by tag, such as tools that create, update or delete something, and can set different rules for each toolkit or tool. When the agent calls one of those tools, Composio does not run it. It asks the user to approve the call, runs the tool once the user answers, and passes a decline or cancel back unchanged, and an MCP client that cannot ask can be set to deny or allow by default.

Approvals arrived in October 2026 and are still marked experimental. Firewall adds checks written in plain language that block a tool call before it runs or a result before the agent sees it, with a built in check for prompt injection in tool results. The customer also chooses which toolkits and tools a session exposes, and scoped API keys keep session management apart from tool execution.

End users authorize each integration for themselves in the Connect Portal and can be shown or particular workflows through Workflow Permissions, and the customer controls which actions its product exposes. Those settings limit what an agent may do, but there is no step where a person reviews, approves or validates an agent action before it commits.

Composio is SOC 2 Type II attested and ISO 27001:2022 certified, with the SOC 2 report and sub processor list in its Trust Center at trust.composio.dev. Access controls include organization and project isolation, scoped project API keys that keep session management apart from tool execution with an IP allowlist for each key, MFA an organization admin can enforce, and signed webhook deliveries.

Credentials stay out of the model's context, APIs no longer return connected account tokens or custom OAuth client secrets, OAuth credentials use envelope encryption, and API keys are stored only as hashes. Composio disclosed a security incident in May 2026, in which an attacker reached internal systems and customer credentials, and its September update lists that remediation, a rebuilt tool building service and independent assessors who re-verified the fixes. Enterprise adds SAML or OIDC SSO with SCIM provisioning and customer managed keys.

Compliance covers SOC 2 Type II, HIPAA and GDPR, and the plans include GDPR and SOC 2 compliance as a feature. A Trust Center and security documentation cover encryption standards, access control and a signable DPA. On the access side there is SAML based SSO on Enterprise, managed OAuth and API key authorization per end user through the Connect Portal with signed user tokens, and workflow permissions restricting which users or groups see which integrations.

Every tool execution and trigger event is logged with the toolkit and action, status, connection and auth config IDs, the supplied user ID, timing and source, and by default the request arguments and response data, kept for up to a year. Enterprise sets its own retention, from 7 days to a year, and zero data retention keeps only metadata. A Logs API and both SDKs search records by user, tool and status, and records export as CSV or into a SIEM or observability platform.

Monitoring gives per-event visibility across the integration stack. It keeps searchable atomic logs of every project event, ActionKit tool-call logs with payloads inspected in real time, trigger subscription events and payloads, workflow executions with step-by-step breakdowns and failure details, and a Connected Users dashboard of each user's connection health. Events route to the customer's own stack through Event Destinations (Slack, Datadog, New Relic, Sentry) and the Task History API.

Customers choose among four deployment options, each with its own credential boundary. Besides Composio Cloud there is a private VPC deployment inside the customer's network boundary, a self hosted deployment in the customer's environment with Helm support, and a deployment with customer managed keys, where a proxy in the customer's cloud holds credential plaintext under keys in its own KMS (AWS KMS, Google Cloud KMS or HashiCorp Vault Transit).

Hosting runs either in Paragon's own cloud or entirely on the customer's infrastructure. On premises hosting comes with a managed instance configuration, and the Enterprise plan includes self hosting and forward deployment.

There is no agent or workflow a customer adopts whole. Composio ships toolkits and meta tools that let an agent find and run actions, plus example applications. Its skills are execution playbooks for single tasks, such as sending a Slack message, derived from real usage and returned with tool search as ordered steps and known pitfalls. Nothing is installed or chosen, so they guide the customer's own agent rather than arriving as ready made workflows, templates or agents for particular roles.

The connector catalog and action library give an agent actions to call, but these are integration capabilities, not packaged assets. The use case library offers implementation guides, not assets a customer adopts. Paragon has no ready made workflows, templates or role specific agents of its own.

The agent and its model stay entirely the customer's. Composio never proxies the customer's LLM or runs an agent on its behalf, and its provider adapters serve tools to whatever framework and model the customer runs, so the model is the customer's choice throughout.

Paragon serves integration actions to whatever model or framework the customer runs. ActionKit is delivered as an API or MCP server with agent optimized schemas and is used from the customer's own agent code. Paragon has no model of its own, so the model is the customer's choice throughout.

Developers get Python and TypeScript SDKs, a CLI, a current REST API (v3.1) with a published reference, provider adapters for the major agent frameworks, sessions exposed over MCP, single-toolkit MCP servers and an agent skill for wiring Composio into a coding agent.

The platform is built for developers. Its APIs and SDKs include a front end Connect SDK, headless Connect Portal APIs, the ActionKit and Sync APIs with published OpenAPI specs, a Permissions API and a Task History API. Builders also get a custom integration builder, custom actions, a hosted demo environment and a self hostable MCP server.

There is no evaluation harness, scored test cases, quality gate or optimization loop after deployment for the customer's agent. Composio's guidance covers building, authenticating and running tools, with advice on production readiness and rate limits, but no gate or debugging path for agent behavior.

Changes move through Release Environments, which test and deploy them before production, and versioned releases name breaking changes. A hosted demo environment and an ActionKit playground let teams try actions, and logs help debug failures. There is no way to score a change, such as test cases, a pass rate or a judge verdict.

Composio's Browser Tool gives an agent a cloud browser for sites with no API. The agent hands it a task in plain language, and a browser agent navigates, clicks, fills forms, handles multi step logins and returns the data or any files it produced.

A live link lets the user watch the browser as it works, a session can be reused so logins and cookies carry over to the next task, and a stuck task can be stopped. The agent sets the task rather than steering each step, and there is no desktop or remote computer session. Separately, the sandbox runs code, which is code execution rather than computer use.

Paragon reaches third party apps through their APIs and its own connectors. It runs no browser, desktop or remote computer session for an agent, and no headless fetch or third party browser engine is wired in.
