Authentication & setup
Authentication & scopes
How the Linkeddit MCP server authenticates requests and what each scope grants.
Authentication methods
- Header credentials: send
X-Client-IdandX-Client-Secret(orAuthorization: Bearer <client_id>:<client_secret>). - OAuth 2.1 connector: Claude.ai connectors use the full authorization-code + PKCE flow; no manual keys required.
Secrets are stored SHA-256 hashed and compared timing-safe. Treat your Client Secret like a password.
Scopes
Each credential carries a set of scopes. New keys are granted the full set; the legacy reddit:read scope also grants every read scope for backward compatibility.
| Scope | Grants |
|---|---|
| reddit:read | Reddit search + subreddit discovery |
| leads:read | Leads, pipelines, projects, stats |
| keywords:read | Keyword autocomplete, SERP, jobs, results |
| compete:read | Competitive-intelligence tools (also needs the Compete plan) |
| content:write | Generate content topics, DM drafts |
| leads:write | Create lead pipelines |
Tier & quota gating
Competitive-intelligence tools require the Compete or Enterprise plan regardless of scope. Tools that create work (create_lead_pipeline, generate_content_topics) consume your account's execution quota and are rate limited.
