# How to connect Le Chat to LinkedIn, step by step Source: https://finchreach.com/guides/mistral 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 Le Chat with the header `Authorization: Bearer lk_…`. Test with a read, and approve the first draft under Approvals. ## What you need - A Finchreach account (sign in at [finchreach.com](https://finchreach.com/sign-in)) and the LinkedIn account you want Le Chat to work on. - Le Chat (only an admin can add connectors (on Free, Pro and Student, the account owner is the admin)). - 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 “Le Chat”. 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 Le Chat 1. Open Connectors → + Add Connector → Custom MCP Connector. 2. Enter a name without spaces (`finchreach`), the URL `https://mcp.finchreach.com/mcp` and a short description, then click Connect. 3. Le Chat detects the authentication method and asks for a token: choose HTTP Bearer Token and paste `lk_YOUR_KEY`. 4. Turn the connector on in a chat and ask for something on LinkedIn. Le Chat connector: ```text Name: finchreach URL: https://mcp.finchreach.com/mcp Auth: HTTP Bearer Token = lk_YOUR_KEY ``` > Replace `lk_YOUR_KEY` with your key. Keep the key out of shared files and repos; where Le Chat can read it from an environment variable, prefer that. Le Chat supports None, Bearer or Basic (sent in `Authorization`) and OAuth 2.1, so the Finchreach key works as a Bearer token. Streamable HTTP over valid TLS, which Finchreach uses. Requirements: Only an admin can add connectors (on Free, Pro and Student, the account owner is the admin). ## Step 4: Test the connection In Le Chat, 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. Le Chat can check the result with `linkedin_get_action`: pending, approved, rejected, executed, failed or expired. ## Troubleshooting - Names can’t contain spaces. Paste the key alone: Le Chat adds `Bearer `. - 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?

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 Le Chat see my LinkedIn password? No. Le Chat 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 “Le Chat”) lets you revoke one without breaking the others. ### How do I disconnect Le Chat? Revoke its key under [API keys](https://finchreach.com/api-keys); Le Chat gets a 401 from then on. Then remove the server from its config. ## Sources - [Le Chat docs](https://docs.mistral.ai/le-chat/knowledge-integrations/connectors/mcp-connectors) ## Related - [What Le Chat can do on LinkedIn](https://finchreach.com/integrations/mistral) - [Write bilingual LinkedIn posts with Mistral Le Chat](https://finchreach.com/blog/mistral-linkedin-bilingual-posts) - [Quickstart and tools](https://finchreach.com/docs) - [All setup guides](https://finchreach.com/guides)
