CoreBridge API & MCP Access

Last Updated: June 2026

1. How Access Works

One program, one meter. Both the REST API and the MCP server draw from a single monthly pool of request credits tied to your plan. Each API call uses 1 credit; each MCP tool call uses 5 credits. You never have to choose between API and MCP, or track two separate quotas — there is one balance to watch, and MCP is included in every tier, including Free.

Included with your license. Every active CoreBridge license includes Free-tier access automatically. The Free tier provides full access to all endpoints and MCP capabilities for development, testing, and evaluation. It is not intended for sustained production use; customers running active integrations will typically upgrade to a paid plan to accommodate real-world volumes.

Plans at a Glance

Feature access by tier: Free and Starter use API-key authentication. Professional adds OAuth 2.0, webhooks, and bulk operations; Business adds JWT, IP allowlisting, audit logs, and advanced analytics; Enterprise adds SSO/SAML and custom endpoints. Concurrent connection limits scale with tier — 2 (Free), 5 (Starter), 10 (Professional), 25 (Business), custom (Enterprise). All tiers include full endpoint and MCP coverage and API-key rotation; the Free tier operates in the production environment only, while paid tiers add a sandbox.

2. Usage Limits & Overage

You are responsible for monitoring your own usage against your plan's monthly credit allowance. The Free tier pauses at its included allowance until the next billing cycle or an upgrade; all paid tiers continue without interruption and bill overages as described below.

Overage Pricing

Overage is metered per 1,000 credits (rounded up) and billed in arrears at the start of the following month. The Free tier has no overage — usage pauses at the cap.

Resets & upgrades. Credits reset on the first day of each billing cycle; unused credits do not roll over. Upgrading mid-cycle takes effect immediately — new limits apply at once, any pause is lifted instantly, and the price difference is prorated for the remainder of the cycle.

Bandwidth

Fair-Use Throttling

To protect platform stability, CoreBridge may temporarily apply rate limits below published levels during periods of exceptionally high aggregate demand or system stress. Any such throttling will be applied as narrowly and briefly as practicable, and will not count toward SLA commitments in Section 4.

3. Support & Onboarding

Priority definitions (paid tiers): P1 — Critical: API/MCP unavailable or data integrity at risk. P2 — High: major feature impaired with a workaround. P3 — Medium: minor issue or general question. P4 — Low: documentation question or feature request. Enterprise response times are defined in the customer's service agreement.

Additional onboarding hours: $250/hr (Starter, Professional), $200/hr (Business, Enterprise).

4. Service Level Agreement

Uptime commitments apply to paid tiers. The Free tier is provided on a best-effort basis with no uptime guarantee.

Service Credits

If CoreBridge fails to meet the uptime commitment for a paid tier, the customer is eligible for service credits applied to the next billing cycle. Credits must be requested within 30 days of the incident and do not exceed 50% of the monthly fee for the affected period.

SLA Exclusions

• Scheduled maintenance, communicated at least 48 hours in advance.
• Force majeure events.
• Issues caused by the customer's own systems or code.
• Third-party service outages beyond CoreBridge's control.
• Beta or preview features.
• Temporary protective throttling during periods of exceptionally high aggregate demand or system stress, as described in Section 2.

5. Acceptable Use

Access applies to your own CoreBridge data only.

Permitted Use

• Integrating your CoreBridge data with your own internal systems.
• Building custom workflows, reports, and dashboards from your CoreBridge data.
• Connecting approved AI assistants, partner apps, or custom integrations via the MCP server.
• Syncing data between CoreBridge and authorized third-party platforms.
• Developing and testing integrations in the sandbox environment (paid tiers).

Prohibited Use

• Reselling, sublicensing, or redistributing API or MCP access to third parties.
• Using access to build a competing product or service.
• Circumventing rate limits, authentication, or security measures.
• Excessive or unnecessary requests intended to degrade system performance.
• Accessing data belonging to other CoreBridge customers.
• Scraping, harvesting, or bulk-downloading data beyond stated integration needs.
• Any use that violates applicable laws or regulations.

6. Authentication & Security

• All communication must use HTTPS (TLS 1.2+). Plain HTTP requests are rejected.
• API subscription keys must be kept confidential and never exposed in client-side code or public repositories.
• The number of API keys a customer may create scales by tier: 1 (Free), 1 (Starter), 10 (Professional), 25 (Business), and unlimited (Enterprise).
• Customers are responsible for securing their keys; CoreBridge is not liable for unauthorized access from compromised credentials.
• Keys can be rotated at any time through the CoreBridge Management system.

7. Versioning & Deprecation

Versioning. The CoreBridge API and MCP interface are versioned. Customers can specify the version in their requests, and older versions continue to function during the deprecation period.

Deprecation notice. A minimum of 6 months' notice is provided before any version is retired or a breaking change is introduced.

Migration support. Documentation and migration guides are provided for all version upgrades. Professional tier and above receive direct migration assistance.

Changelog. A public changelog is maintained in the documentation portal, detailing all additions, changes, and deprecations.

8. Billing & General Terms
