Open scheduling infrastructure giving AI agents 18 calendar tools over MCP, A2A and REST, with deterministic time logic, cross-calendar availability and atomic booking.

Temporal Cortex is open scheduling infrastructure for AI agents. It gives an agent 18 tools in five layers, from resolving "next Friday at 3pm" to an exact timestamp, through reading and merging availability across Google Calendar, Outlook and CalDAV calendars such as iCloud, to booking.

Its Truth Engine expands recurrence rules deterministically, and book_slot books atomically with a two-phase commit, locking the slot, checking for conflicts, writing the event and rolling back on failure, so concurrent agents cannot double-book.

Tools are reached through an MCP server, A2A for agent-to-agent negotiation, a REST API with API keys, and Temporal Links that serve a booking page to people and JSON to agents.

The local MCP server runs free on the user's machine with no account. The managed platform adds OAuth management, multi-agent coordination, a dashboard, an activity feed and usage metering, the Open Scheduling network, and caller-based policies that auto-accept, hold for approval or block booking requests. Enterprise adds SSO through SAML and OIDC, US or EU data residency, audit log export to a SIEM, and self-hosting of the full platform with Docker Compose or Terraform. The Enterprise page says Temporal Cortex is designed for SOC 2 Type II compliance and offers a HIPAA BAA.

Its MCP repository is MIT licensed, and it describes its core Truth Engine and TOON libraries as MIT or Apache-2.0. Individuals get a free Starter plan with 20 bookings a month or Pro at $19 a month; developers get a free Starter plan with 100 bookings a month, Growth at $29 and Scale at $99 with prepaid booking bundles and per-booking overage, and a custom Enterprise plan.

Integrations

Google Calendar and Microsoft Outlook through OAuth 2.0, CalDAV calendars such as iCloud, Fastmail and Nextcloud, and contact search across Google People and Microsoft Graph; served over MCP (stdio and HTTP), A2A, a REST API and Temporal Links; framework guides for LangGraph, CrewAI and the OpenAI Agents SDK; packages on npm, crates.io and PyPI.

In practice

Your agent keeps booking the wrong Tuesday or double-booking. Temporal Cortex resolves dates deterministically, merges availability across Google, Outlook and iCloud, and books atomically so two agents cannot take the same slot.

You are adding interview or meeting scheduling to your product. The REST API and MCP tools give your agent availability and booking across your users' calendars, with prepaid booking bundles from $29 a month.

Other people's agents need to book time with your team. A Temporal Link answers agents in JSON and people with a booking page, and your policies decide which requests are accepted, held for approval or blocked.

Integrations & Tool Calling Full

Agents get 18 scheduling tools over Google Calendar and Microsoft Outlook (OAuth 2.0) and CalDAV calendars such as iCloud and Fastmail, including contact search across Google People and Microsoft Graph and a book_slot tool that writes events, reached through the vendor's MCP server, A2A or the REST API. Those are authenticated read and write actions in the customer's calendars.

Sourcetemporal-cortex.com/llms-full.txtread 2026-09-22

Workflow Orchestration Partial

A multi-step booking is carried out by Temporal Cortex itself: book_slot locks the slot, verifies there is no conflict, writes the event and releases the lock, rolling everything back if a step fails, with distributed locking coordinating concurrent agents on the managed platform.

The customer's agent sequences the other tools, following a documented orient, resolve, query and book pattern, inside its own framework. That is a vendor run transaction with rollback that is safe to retry; no workflows that combine deterministic nodes with autonomous agent steps, with branching and routing, are documented.

Sourcetemporal-cortex.com/llms-full.txtread 2026-09-22

Knowledge Grounding & RAG Not documented

There is no retrieval structure over the customer's documents or knowledge. Contact search queries Google People and Microsoft Graph live, and the availability tools read calendars live; both are live integration rather than grounding. No ingestion, indexing, retrieval or RAG layer over company data is documented.

Sourcetemporal-cortex.com/llms-full.txtread 2026-09-22

Human Oversight & Guardrails Full

A person can be put in front of an agent's booking: when another agent sends request_booking, the recipient's policies decide whether it is auto-accepted, held for the recipient's approval or blocked, and the API's booking rules carry a confirm_before_booking setting beside minimum notice and advance-booking limits.

Policies set per caller domain or trust level allow or deny requests by priority, and the content firewall strips injection attempts before any tool runs. So an approval step can sit before an agent's booking commits, inserted at the policy layer; how the approval request reaches the person is not described.

Sourcetemporal-cortex.com/llms-full.txtread 2026-09-22

Security, Identity & Governance Partial

Access controls run deep: SSO through SAML and OIDC with Okta, Azure AD and Google Workspace, multi-user organization and seat management, API keys stored only as SHA-256 hashes, caller-based policy enforcement on every request, TLS 1.3 and encryption at rest with per-organization schemas, and audit log export to a SIEM, several of them on the Enterprise tier.

The compliance claim is hedged: the Enterprise page's answer to whether Temporal Cortex is SOC 2 compliant is that it is designed for SOC 2 Type II compliance, although a card on the same page reads SOC 2 Type II Compliance, and a HIPAA BAA is a contract offer, not an attestation. No SOC 2 report is published.

Sourcetemporal-cortex.com/enterpriseread 2026-09-22

Observability & Auditability Full

On the managed platform, what agents do is recorded: an activity feed of booking and calendar activity per tenant, a dashboard and daily usage metrics counting bookings and API calls, and, on Enterprise, audit log export with SIEM integration and custom retention policies. The activity feed covers bookings rather than every read the agent made.

Sourcetemporal-cortex.com/docs/rest-apiread 2026-09-22

Memory & State Persistence Not documented

Settings, booking rules, caller profiles with trust levels and policies are stored, but the platform applies them as rules to each request rather than as context an agent reads to decide, and its distributed locks last only for a booking. No memory layer that keeps an agent's context across runs is documented.

Sourcetemporal-cortex.com/docs/rest-apiread 2026-09-22

Deployment & Data Residency Full

Three deployment modes are documented: a local MCP server started with npx that keeps credentials on the user's machine, the managed platform, and a full self-hosted platform (API, MCP server, database and portal) through Docker Compose or Terraform modules on AWS, GCP or Azure; Enterprise customers can choose US or EU data residency.

Sourcetemporal-cortex.com/enterpriseread 2026-09-22

Prebuilt Agents / Templates / Packs Partial

The vendor's own Agent Skills (router, datetime and scheduling) load a ready-made scheduling workflow into Claude, Cursor and other agent platforms, and Enterprise admins can provision skills and policies to users. These are working assets for one workflow; there is no browsable catalog of ready-made workflows, templates or role specific agents, and the use case pages (recruiting, sales, healthcare and others) are guides, not assets a buyer adopts.

Sourcetemporal-cortex.com/llms-full.txtread 2026-09-22

Triggers & Channel Coverage Partial

Scheduling requests reach a Temporal Cortex user through several channels: a Temporal Link that serves a booking page to people and JSON to agents, A2A Agent Cards for agent-to-agent negotiation, MCP tools and the REST API, with the owner's policies deciding each request. Those requests are handled by the platform's rules, and nothing documented starts the customer's own agent on an event or a schedule; the webhooks in the API reference are inbound sign-up and billing events for Temporal Cortex's own operations.

Sourcetemporal-cortex.com/open-schedulingread 2026-09-22

Model Flexibility & Routing Full

The tools work with whatever model and agent the customer runs: Claude Desktop, Cursor, OpenClaw, Manus or any MCP client, and LangGraph, CrewAI and the OpenAI Agents SDK in the developer guide, each with the customer's own model. Temporal Cortex names no model of its own and computes time deterministically rather than through a model, so model choice is the customer's throughout.

Sourcetemporal-cortex.com/developersread 2026-09-22

APIs / SDKs / MCP Extensibility Full

Outside callers use a documented REST API with Bearer API keys (calendars, availability, bookings, events, settings, callers, policies, keys and usage), an MCP server over stdio and streamable HTTP, A2A for agent-to-agent negotiation, and packages on npm, crates.io and PyPI, with TypeScript and Python SDKs named in the vendor's llms.txt.

Sourcetemporal-cortex.com/docs/rest-apiread 2026-09-22

Testing, Debugging & Optimization Not documented

Temporal Cortex publishes its own comparison of frontier models against its Truth Engine on recurrence rules and states its own test counts; both describe the vendor's product, not a way for the customer to test its agent. No fixtures, datasets, scoring or quality gate for the customer's agent workflows is documented.

Browser / Computer-use Not documented

Temporal Cortex's browser channel is a booking page where people pick a slot on a Temporal Link, and its tools reach calendars through provider APIs. No browser, desktop or computer control by an agent is documented.

Pricing

Free local and Starter · Developer Growth $29/mo + $0.10 per extra booking · Scale $99 · Enterprise custom (individual Pro $19/mo)

Successful bookings: monthly plans with prepaid booking bundles and per-booking overage; reads and availability checks free

Free tier

Included quota

Developers: Starter 100 bookings a month and 1,000 API calls a day; Growth 500 bookings and 10,000 calls a day; Scale 2,000 bookings and unlimited calls. Individuals: Starter 20 bookings a month; Pro unlimited. Reads, availability and time calculations are unlimited on every tier.

What is public

Every self-serve tier is priced with its bundle, API limits and overage; only Enterprise is custom.

Billing mechanics

Run the local server for free, or sign up for the managed platform: free Starter tiers, then monthly plans that include a prepaid bundle of bookings with a per-booking overage you can cap, or a custom Enterprise contract.

Cost watchouts

Successful bookings beyond the prepaid bundle bill at $0.10 (Growth) or $0.08 (Scale) each, with a budget cap and an overage toggle in the dashboard. SSO, data residency, audit export and self-hosting of the full platform are Enterprise features.

Variable cost rationale

Only successful bookings are metered, so cost tracks booking volume past the prepaid bundle; reads and availability checks are free, and a budget cap limits overage.

Overage / add-ons

$0.10 per booking over the bundle on Growth, $0.08 on Scale; budget cap and overage toggle in the dashboard; failed or conflicted bookings are free.

Sales call required

Mixed (some tiers require a call)

Free / trial

Local MCP server free with no account; managed Starter free (100 bookings a month for developers, 20 for individuals)

Lowest paid plan

Developer Growth, $29 a month with 500 bookings, then $0.10 per booking (individual Pro is $19 a month)

Commercial notes

Self-serve checkout through Stripe for paid tiers; Enterprise adds SSO, US or EU residency, audit export, self-hosting and an SLA.

Key ambiguities

Enterprise terms are custom. The Enterprise page lists SOC 2 among its features but describes Temporal Cortex as designed for SOC 2 Type II compliance.
