# How to connect Microsoft Copilot to LinkedIn, step by step Source: https://finchreach.com/guides/copilot Third-party facts checked on 2026-10-28. Create an API key at finchreach.com/api-keys, connect LinkedIn at finchreach.com/accounts, then add `https://mcp.finchreach.com/mcp` to Microsoft Copilot with the header `Authorization: Bearer lk_…`. Test with a read, and approve the first draft under Approvals. One caveat: it works in Copilot Studio (a paid license on a work account), not in consumer Microsoft Copilot. ## What you need - A Finchreach account (sign in at [finchreach.com](https://finchreach.com/sign-in)) and the LinkedIn account you want Microsoft Copilot to work on. - Microsoft Copilot (a paid Copilot Studio license or a trial, on a work account. Power Platform data policies apply). - About five minutes. ## Step 1: Create a Finchreach API key 1. Sign in at finchreach.com and open [API keys](https://finchreach.com/api-keys). 2. Create a key and name it after the tool, for example “Microsoft Copilot”. 3. Copy it right away: it starts with `lk_` and is shown only once. ## Step 2: Connect your LinkedIn account 1. Open [Accounts](https://finchreach.com/accounts) and click to connect LinkedIn. 2. Follow the steps until the account shows as connected. Approval mode is on by default: nothing the assistant drafts reaches LinkedIn until you approve it. ## Step 3: Add Finchreach to Microsoft Copilot 1. In Copilot Studio, open your agent → Tools → Add a tool → New tool → Model Context Protocol. 2. Enter a name, a description and the URL `https://mcp.finchreach.com/mcp`. 3. Authentication: API key, type Header. Use the header name `X-API-Key` (or `Authorization`). Create, then Add tool. 4. Create a new connection and enter the key: `lk_YOUR_KEY` for `X-API-Key`, or `Bearer lk_YOUR_KEY` if you chose `Authorization`. Add it to the agent. Copilot Studio API key settings: ```text Header name: X-API-Key Key value: lk_YOUR_KEY (or) Header name: Authorization Key value: Bearer lk_YOUR_KEY ``` > Replace `lk_YOUR_KEY` with your key. Keep the key out of shared files and repos; where Microsoft Copilot can read it from an environment variable, prefer that. Copilot Studio offers None, API key (in a header or the query) and OAuth 2.0. Microsoft’s docs don’t say whether it adds `Bearer ` to an `Authorization` key, so the `X-API-Key` header, which Finchreach accepts with the bare key, avoids the question. Consumer Copilot has no documented way to add an MCP server. Requirements: A paid Copilot Studio license or a trial, on a work account. Power Platform data policies apply. ## Step 4: Test the connection In Microsoft Copilot, start with a read. It runs right away and proves the key and the account work: > Ask your assistant: “List my connected LinkedIn accounts, then summarize my five latest notifications.” You should see calls to `linkedin_list_accounts` and `linkedin_get_notifications`. Then try a write, which goes to your approval queue instead of LinkedIn: > Ask your assistant: “Draft a short LinkedIn post saying I’m trying a new AI assistant workflow. Submit it for my approval.” ## Step 5: Approve or reject it in Finchreach 1. Open [Approvals](https://finchreach.com/approvals). The draft is there with its exact text and the account it would go out from. 2. Approve it to publish, or reject it (reject the test post if you don’t want it live). 3. Microsoft Copilot can check the result with `linkedin_get_action`: pending, approved, rejected, executed, failed or expired. ## Troubleshooting - If the connection test fails with `Authorization`, try `X-API-Key` with the bare key, or add or remove the `Bearer ` prefix. - Your tenant’s Power Platform data loss prevention policy can block custom connectors; ask your admin. - 401 or “unauthorized”: the key is wrong, revoked or missing its prefix. Finchreach accepts `Authorization: Bearer lk_…` or `X-API-Key: lk_…`; check for a missing `Bearer `, quotes or a trailing space. - A tool is missing: the key’s permissions don’t include it. Create a key with the permissions you need under [API keys](https://finchreach.com/api-keys). - “No LinkedIn account”: connect one under [Accounts](https://finchreach.com/accounts), or reconnect it if its session expired. - A post or message “didn’t go out”: it is probably still waiting under [Approvals](https://finchreach.com/approvals). Writes run only after you approve them. Still stuck? Compare your setup with [Microsoft Copilot’s documentation](https://learn.microsoft.com/en-us/microsoft-copilot-studio/mcp-add-existing-server-to-agent), checked on 2026-10-28; client screens change often. ## What to ask Microsoft Copilot next > Ask your assistant: “Build an agent that drafts a weekly LinkedIn post from our team’s Friday update, for my approval.” > Ask your assistant: “Summarize my LinkedIn messages from partners and list the ones waiting for a reply.” > Ask your assistant: “Draft connection invitations to the attendees on this event list, with a one-line note each.” More ideas on the [Microsoft Copilot integration page](https://finchreach.com/integrations/copilot). ## Questions ### I lost my API key. Can I see it again? No, a key is shown only once. Create a new one under [API keys](https://finchreach.com/api-keys), put it in your config, and revoke the old one. ### Does Microsoft Copilot see my LinkedIn password? No. Microsoft Copilot only gets your Finchreach API key. Your LinkedIn connection stays in Finchreach, and you can revoke the key at any time without touching LinkedIn. ### Can I use the same key in several tools? Yes, but one key per tool (for example one named “Microsoft Copilot”) lets you revoke one without breaking the others. ### How do I disconnect Microsoft Copilot? Revoke its key under [API keys](https://finchreach.com/api-keys); Microsoft Copilot gets a 401 from then on. Then remove the server from its config. ## Sources - [Microsoft Copilot docs](https://learn.microsoft.com/en-us/microsoft-copilot-studio/mcp-add-existing-server-to-agent) ## Related - [What Microsoft Copilot can do on LinkedIn](https://finchreach.com/integrations/copilot) - [A Monday LinkedIn briefing with Microsoft Copilot Studio](https://finchreach.com/blog/copilot-linkedin-monday-briefing) - [Connect GitHub Copilot](https://finchreach.com/guides/github-copilot) - [Quickstart and tools](https://finchreach.com/docs) - [All setup guides](https://finchreach.com/guides)
