# Nango — Handles OAuth for 1,000+ APIs and runs your TypeScript integration functions, exposed to agents over MCP. > Source: The Agents Index — https://theagentsindex.com/nango (structured, researched, re-verified) Nango is an integration platform that handles OAuth, credentials and token refresh for 1,000+ external APIs and runs integration logic written or AI-generated as TypeScript functions. Agents reach those functions through scoped sessions that each expose their own MCP server. **Best for:** Engineering teams shipping many customer-facing API integrations and agent tool calls | Fact | Value | | --- | --- | | Website | https://nango.dev | | Category | Tool integrations & auth | | Open source | Yes | | Price | Free | | Price source | https://nango.dev/pricing | | Price checked | 28 October 2026 | | MCP server | Yes | | API | Not stated | | Self-host | Yes | | Facts | 20 facts from 7 sources | | Facts checked | 28 October 2026 | Screenshot of Nango: https://theagentsindex.com/img/1920/screenshots/nango.webp, captured 30 October 2026 **What we checked** - Pages last read: 28 October 2026 - Facts checked: 20 facts (From 7 sources) - AI answers: Named in 1 of 151 (Our October check) ## What we checked on Nango ### How much it does unattended **Agent permissions** · Yes — Sessions are immutable and least-privilege by construction: toolsets can be narrowed to named tools per integration, the raw proxy meta tool is off unless you turn it on, and sessions expire (minimum 60s, default and maximum 15 days) or can be killed early. > "meta_tools": { // Optional. nango_proxy is off unless you turn it on > — https://nango.dev/docs/guides/agent-sessions · Session basics, Creating a session configuration block, checked 28 October 2026 ### Which models it runs on **Model choice** · Yes — Nango hosts no model and takes no view on yours: the session MCP endpoint is plain Streamable HTTP, so whichever client or provider you already use connects to it, and the docs show OpenAI, Anthropic, Vercel AI SDK, LangChain and Mastra wiring. > so any MCP-capable agent or client can connect to it > — https://nango.dev/docs/guides/agent-sessions · Session basics, Session MCP server subsection, checked 28 October 2026 ### Whose machine it runs on **Self-hosted** · Yes — Three ways off the vendor's cloud: a free Docker Compose build limited to Auth and Proxy, BYOC where Nango operates the instance in your AWS, GCP or Azure account, and Self-Managed via a Helm chart on your own Kubernetes — the latter two Enterprise-only. > Nango offers two ways to run outside of Nango Cloud, both on the Enterprise plan: > — https://nango.dev/docs/guides/platform/self-hosting/self-hosting · Self-host Nango, opening line above the BYOC and Self-Managed bullets, checked 28 October 2026 **Open source** · Yes — The platform's source is public on GitHub and the vendor calls it open source, but the licence is the Elastic License rather than an OSI-approved one, and the freely self-hostable build is deliberately feature-limited against Cloud. > Nango is available under the [Elastic License](https://github.com/NangoHQ/nango/blob/master/LICENSE). > — https://github.com/NangoHQ/nango · README, 'Open-source vs. paid' section, checked 28 October 2026 ### Building with it **SDK languages** · Partly — TypeScript is the only shipped SDK: integration logic is written as TypeScript functions and the backend SDK is published as @nangohq/node. The Python, Go, Java, Ruby, Rust and PHP reference pages each say coming soon and point you at the REST API instead. > Coming soon. Use the [REST API](https://nango.dev/docs/reference/backend/http-api/authentication.md) in the meantime. > — https://nango.dev/docs/reference/backend/backend-sdk/python · Backend SDK: Python reference page, note at top, checked 28 October 2026 **Tracing and evals** · Yes — Every operation in the account produces a log entry with its integration, connection and function, filterable in the dashboard, and traces for syncs, actions, webhooks and proxied requests export over OpenTelemetry; logs are deleted after 15 days and the free self-hosted build covers auth and proxy only. > **Comprehensive**: Everything that happens in Nango for your integrations produces an "operation" in the logs > — https://nango.dev/docs/guides/platform/observability · Our approach section, principles list, checked 28 October 2026 ### What it costs to run **How it meters** · Yes — Three usage meters, no seats: connections billed per authorised end-user account per month and prorated, function compute billed per hour of execution rounded up to the nearest second, and egress data transfer billed per GB with ingress free. > Each connection represents one authorized user account (for example, one user’s Salesforce account). Billed per connection per month, prorated for the time the connection exists. > — https://nango.dev/pricing · Rates & limits, Connections column tooltip, checked 28 October 2026 **Cost of one job** · Yes — On the cheapest paid plan a job is priced in three meters rather than one: $0.29 per connection per month, $0.72 per hour of function compute rounded up to the second, and $0.50 per GB of egress, on top of the $50 monthly fee which itself buys $50 of credits. > Pay-as-you-go $0.29 / connection $0.72 / hour $0.5 / GB > — https://nango.dev/pricing · Rates & limits table, Pay-as-you-go row, checked 28 October 2026 **Free tier** · Yes — A standing Free plan at $0/mo covers API and MCP auth, tools and syncs with hard-capped monthly limits, and you can sign up and build without talking to anyone; only Enterprise terms need a call. > Free $0 /mo API & MCP auth, tools & syncs Hard-capped limits, reset monthly > — https://nango.dev/pricing · Plans section, Free plan card, checked 28 October 2026 **MCP server** · Yes — Two MCP surfaces: every agent session serves its own Streamable HTTP MCP endpoint authenticated by the session token, and a separate Management MCP server lets a client administer the account and query logs. The free self-hosted build excludes MCP. > Every session exposes its own MCP server at its `mcp_url`. It speaks Streamable HTTP and authenticates with the `session_token` as a bearer token, so any MCP-capable agent or client can connect to it. > — https://nango.dev/docs/guides/agent-sessions · Session basics, Session MCP server subsection, checked 28 October 2026 **Bring your own key** · Yes — You can bring your own OAuth apps instead of Nango's pre-approved ones on any plan, and bring your own cloud account for the whole instance, though that second route (BYOC or Self-Managed) is Enterprise-only. No model keys are involved: Nango runs no inference of its own. > Use pre-approved OAuth apps or bring your own for a fully white-label experience. > — https://nango.dev/pricing · Features comparison, 'Nango-managed & self-managed apps' row description, checked 28 October 2026 ### Buying it for a team **A company can buy it** · Yes — There is a real organisation path: an Enterprise plan with commitment discounts, a master services agreement and an SLA, plus team roles, SAML SSO, SCIM and an audit trail for the buying side, and self-serve plans for teams that do not need paper. > Enterprise Custom pricing Discounts with commitments Self-hosting, MSA, SLA > — https://nango.dev/pricing · Plans section, Enterprise plan card, checked 28 October 2026 **Seat model** · No — There is no seat price and no seat floor: the vendor states its billing metrics exhaustively as connections, compute time and data transfer, so adding team members does not change the bill, though dashboard roles still govern who may do what. > Start free. Pay only for connections, compute time and data transfer as you grow. > — https://nango.dev/pricing · Pricing hero, subheading under 'Fair and transparent pricing', checked 28 October 2026 **Pooled budget** · Yes — Billing is one account-level pool rather than per-person balances: the Pay-as-you-go fee grants $50 of credits a month spent across whatever connections, compute and data transfer the account uses, with a single usage breakdown and spend alerts in the dashboard. > Pay-as-you-go $50 /mo Pay-as-you-go rates $50 in credits, each month > — https://nango.dev/pricing · Plans section, Pay-as-you-go plan card, checked 28 October 2026 **Admin controls** · Yes — An agent's reach is fixed when your backend mints the session: you pick the tenant connections, the allowed integrations and tools, and which meta tools are on, and the agent cannot widen that itself. Dashboard-side, RBAC limits what each human may change. > Your backend creates the session and exposes it to the agent as an MCP server. The agent never sees raw credentials, and cannot change the scope of its own session. > — https://nango.dev/docs/guides/agent-sessions · Agent sessions, opening section above Quickstart, checked 28 October 2026 **Audit log** · Yes — Control-plane changes are recorded account-wide with the actor, the outcome and the originating IP, entries are immutable, and you can export them as CSV; retention is one year by default and the free self-hosted build has no audit trail. > The audit trail records control-plane changes with actor, outcome, and originating IP: who created or deleted a connection, changed an integration, rotated an API key, or signed in. Entries are immutable and account-wide, exportable as CSV. > — https://nango.dev/docs/guides/platform/security · Data storage, retention & deletion, Audit trail subsection, checked 28 October 2026 **Single sign-on** · Partly — SAML is gated: the Free and Pay-as-you-go plans get Google SSO only, SAML arrives with the $450/mo Growth add-on, SCIM only on Enterprise Cloud, and SAML is not yet available on self-hosted instances. Login must also be started from the identity provider. > Free / Pay-as-you-go Google SSO only > — https://nango.dev/docs/guides/platform/security · Access control, Single sign-on plan table, checked 28 October 2026 ### What happens to your code **Data residency** · Partly — Cloud data sits in a managed PostgreSQL database in AWS and there is no EU cloud today; residency elsewhere means BYOC, which puts the instance in your own AWS, GCP or Azure region but only on the Enterprise plan. > We currently don’t have an EU cloud, but are considering this for the future. Meanwhile we offer BYOC instances in any AWS, GCP or Azure region on the Enterprise plan. > — https://nango.dev/pricing · FAQ, 'Does Nango offer an EU-hosted cloud?', checked 28 October 2026 **Getting out** · Yes — Synced records come back through the records API, logs and traces export over OpenTelemetry to your own stack, and the audit trail exports as CSV; note the vendor's own retention clocks delete logs at 15 days and record payloads at 30 days whether you export or not. > Entries are immutable and account-wide, exportable as CSV. > — https://nango.dev/docs/guides/platform/security · Data storage, retention & deletion, Audit trail subsection, checked 28 October 2026 **Certifications** · Yes — SOC 2 Type II with an annual audit and a report in the trust center, GDPR with a DPA that applies automatically to cloud accounts, and HIPAA with a BAA that the vendor ties to the Growth add-on rather than the entry plans. > Nango is **SOC 2 Type II** certified, **GDPR** compliant, and **HIPAA** compliant. > — https://nango.dev/docs/guides/platform/security · Compliance section, opening sentence and certification table, checked 28 October 2026 ## Nango price and terms **Terms** - Free plan: Yes — Free plan at $0/mo, hard-capped and reset monthly: 10 connections, 10 hours of compute time per month, 10GB of data transfer per month, and 200 API requests per minute. **What needs a higher plan** - Enterprise: Data residency ## For AI agents - MCP server: Yes Pricing page as we captured it: https://theagentsindex.com/img/1920/screenshots/nango/pricing.webp, captured 30 October 2026 Read on https://nango.dev/pricing, 28 October 2026. ## Nango alternatives - [Aident Loadout](https://theagentsindex.com/aident-loadout) · Free plan, then $9.90 a month: Managed capability layer that connects any AI agent to 1,000+ apps through one reusable, audited setup. - [Composio](https://theagentsindex.com/composio) · Free plan, then $29 a month: Managed OAuth, tool discovery and execution across 1,500+ apps for agents you already run. - [Arcade](https://theagentsindex.com/arcade-dev) · Free plan, then $25 a month: Runtime that brokers OAuth, executes MCP tools and audits every agent action against the user's own permissions.
