Glue

Glue is a team communication platform that replaces channel-based chat with structured, named threads so decisions stay organized and don't get lost, with AI agents (@Glue, @Cursor) that can be mentioned inside threads to summarize, add context, and generate work. For developers, Glue exposes a public GraphQL API at api.gluegroups.com for sending messages and reading workspaces, threads, and groups; OAuth 2.0 authentication (client-credentials for the GraphQL API, plus an authorization-code flow with dynamic client registration and PKCE for a hosted remote MCP server at mcp.glue.ai); outbound webhooks (message.created, thread.created) signed with HMAC-SHA256; and idempotent upsert keys on message and thread creation. Glue is SOC 2 compliant, supports SSO (Google, Okta), and is backed by Craft Ventures and Y Combinator.

Glue publishes 1 API on the APIs.io network. Tagged areas include Company, Software-as-a-Service, Team Communication, Messaging, and Collaboration.

The Glue catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Glue’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/glue: open an issue to ask a question, or submit a pull request to add artifacts.
