Guides # REST or MCP for social automation: keep human approval in the path Choose deterministic REST calls or discoverable MCP tools, apply least-privilege scopes, and require a person to approve destinations, copy, media, and time before scheduling.

Choose MCP when an interactive agent needs to discover a small, scoped tool catalog. In either path, begin read-only and require a person to approve the account, copy, media, link, time, and time zone before any external write. ## REST or MCP? __REST and MCP automation decision__ | Need | Prefer REST | Prefer MCP | | ------------------------------- | --------------------------------------------------------------- | ------------------------------------------------------------------ | | NeedRepeatable backend workflow | Prefer RESTTyped endpoint and explicit payload | Prefer MCPOnly if an agent must reason across tools | | NeedInteractive assistant | Prefer RESTPossible but the client must know the contract | Prefer MCPDiscoverable tools and descriptions | | NeedBulk or high-volume work | Prefer RESTBetter fit with controlled queues and retries | Prefer MCPAvoid broad autonomous batches | | NeedHuman draft review | Prefer RESTCreate a draft, render review UI, then call schedule | Prefer MCPAsk for a draft, show it, then require explicit approval | | NeedSecurity boundary | Prefer RESTOAuth or API key scopes and server authorization | Prefer MCPThe same scopes plus tool visibility constrained by them | Naasher provides both paths. The MCP worked example below connects to `https://api.naasher.com/api/mcp` over Streamable HTTP with a read-only key. Verify `channels.list` and `posts.list`, then add write access only when the workflow has an explicit review step. REST clients use the versioned contract under `https://api.naasher.com/api/sdk/v1` and should follow the same scope and approval boundary. We tested this path against Naasher's production environment on 22 August 2026\. A narrowly scoped key authenticated successfully, the server negotiated MCP version `2025-11-25`, and `tools/list` exposed only the two permitted read tools. That is the intended boundary: scopes control what the agent can discover, not merely what fails after it tries. ## 1\. Create a narrowly scoped key Open **Settings → API keys**, create a key, and choose its environment. For a first connection, grant only: - `channels:read` to list connected social accounts. - `posts:read` to list posts with supported filters. Do not add `posts:create`, `posts:schedule`, or `analytics:read` simply because they are available. Give each integration the smallest scope set that completes its job, and use a separate key per client so one can be revoked without interrupting the others. Naasher shows the key secret once. Store it in an environment variable or the client's secret manager, never in a configuration file that will be committed to Git. ## 2\. Add the endpoint to your client Naasher uses [Streamable HTTP](https://modelcontextprotocol.io/specification/2025-06-18/basic/transports), the standard MCP transport that carries JSON-RPC messages through one HTTP endpoint. A generic client configuration looks like this: ```json { "mcpServers": { "naasher": { "type": "http", "url": "https://api.naasher.com/api/mcp", "headers": { "x-naasher-api-key": "" } } } } ``` Replace the placeholder through your client's native secret mechanism instead of committing the key to a file. The server also accepts an `Authorization: Bearer` header. See the [Naasher MCP reference](https://docs.naasher.com/mcp) for current setup and tool details. ## 3\. Verify read access before write access Ask the agent: > List the available tools, then show my connected channels and recent posts. Do not create, change, schedule, or publish anything. With the read-only key, `tools/list` should expose: - `channels.list` - `posts.list` If an unexpected write tool appears, stop the test, revoke the key, and create one with narrower scopes. If a required tool is missing, adjust that key in Naasher instead of sharing a broader key from another integration. ## 4\. Add write access behind a review gate When the agent needs to draft content, add `posts:create`. Add `posts:schedule` only when it must set a publishing time. Have it create a draft first and show the text, channels, time, and time zone before scheduling. A safer request is: > Create an English draft for this LinkedIn announcement and show it with a suggested time. Do not schedule it until I explicitly approve. Prompt wording is not a security boundary; scopes are. Keep research and reporting on a read-only key, and use a separate, short-lived key for work that genuinely needs write access. ## Production checklist - The key belongs to one client and is absent from repositories and messages. - `tools/list` exposes only the tools the workflow needs. - The intended channels, time, and time zone are explicit before scheduling. - A person reviews copy, media, and links before publication. - Someone owns key rotation and revocation when the integration is retired. - Every external write has an application-level idempotency and uncertain-outcome policy; prompt wording is not that policy. - The person approving sees the remote account identity, final copy, media, link, time, and time zone. MCP access is included with **Team** and **Agency** plans. See [pricing in Arabic](/pricing), or continue with the [LinkedIn connection guide](/en/guides/linkedin) if that is your next channel. ## Test the workflow with your real accounts Start free, then compare the composer, calendar, and channel limits with what your team actually needs before choosing a plan.

Create a key in workspace settings and keep it in your client's secret store. Never put the key in a message, repository, or screenshot. What is the safest scope set for a first test? Start with channels:read and posts:read. Create, schedule, and analytics tools do not appear in tools/list unless you explicitly grant their scopes. Can an agent publish as soon as it connects? Not with a read-only key. Publishing and scheduling require additional scopes that you control, and a human review step should remain in front of any external action. ## Read next [![Personal and company Page post cards moving toward one publishing time](/editorial/schedule-linkedin-cover.webp)GuidesLinkedInB2BSchedule LinkedIn profiles and company PagesSchedule LinkedIn posts for a personal profile or company Page, understand the authorization difference, and build a professional content calendar for Gulf audiences.August 15, 2026·4 min read](/en/guides/linkedin) [![Lightweight post cards flowing through a calendar into a publishing queue](/editorial/schedule-bluesky-cover.webp)GuidesBlueskyAT ProtocolConnect Bluesky and schedule posts safelyCreate a Bluesky app password, connect securely, and schedule text, images, and threads with current 300-character and four-image limits.August 15, 2026·4 min read](/en/guides/bluesky) --- Canonical URL: https://naasher.com/en/guides/mcp
