It gives your agent 246 Matrix / Element (Client-Server + Synapse Admin) actions (124 reads, 76 writes and 46 that wait for a confirmation) and holds the Matrix / Element (Client-Server + Synapse Admin) credential itself, so the agent never does. It paces Matrix / Element (Client-Server + Synapse Admin)'s limits and records every call. [Connect Matrix / Element (Client-Server + Synapse Admin) free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing) 100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you. `claude mcp add --transport http actionlake https://connect.actionlake.com/mcp` the first call ``` do { action: "matrix_synapse.admin_users.users_list", intent: "check which Matrix / Element (Client-Server + Synapse Admin) account is connected" } # List user accounts (v2) · read · 1 upstream call ``` - 246 actions in one signed file - 124 read look, never change - 76 write create and update - 46 wait for a yes destructive, confirmed first Set up ## Connect Matrix / Element (Client-Server + Synapse Admin) in three steps. 1. 01 ### Add actionlake to Claude. Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us. `https://connect.actionlake.com/mcp` 2. 02 ### Connect Matrix / Element (Client-Server + Synapse Admin). Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key. - `access_token` Matrix access token, sent as `Authorization - `host` Where your Matrix / Element (Client-Server + Synapse Admin) lives: your host ``` account { op: "connections.requirements", service: "matrix_synapse" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### Make the first call. Check before a write. Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free. ``` do { action: "matrix_synapse.admin_users.users_list" } # list user accounts (v2) · read · 1 upstream call check { action: "matrix_synapse.room_events.send_message", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Matrix / Element (Client-Server + Synapse Admin) at a glance **Sign-in** Bearer token.

Plus your host. The free call account { op: "connections.requirements", service: "matrix_synapse" } lists exactly what to paste. **Can an AI agent delete or change things in Matrix / Element (Client-Server + Synapse Admin)?** Only if its key allows it, and only with an explicit confirmation. 46 Matrix / Element (Client-Server + Synapse Admin) actions are destructive, including kick a user from the room, ban a user in the room and delete a room (v2, background task). Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my Matrix / Element (Client-Server + Synapse Admin) API limit?** actionlake paces every call to the limits in the Matrix / Element (Client-Server + Synapse Admin) service file: 10 calls a second per connection. Repeated reads are answered from cache (121 Matrix / Element (Client-Server + Synapse Admin) actions can be), which never reaches Matrix / Element (Client-Server + Synapse Admin). **What does a Matrix / Element (Client-Server + Synapse Admin) action cost?** One upstream call, the only unit actionlake bills.

Your Matrix / Element (Client-Server + Synapse Admin) credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Matrix / Element (Client-Server + Synapse Admin) Shares the most action names with - [Rocket.Chat 12](https://actionlake.com/connectors/rocket-chat) - [Zulip 10](https://actionlake.com/connectors/zulip) - [Discord 9](https://actionlake.com/connectors/discord) - [Cisco Webex 8](https://actionlake.com/connectors/cisco-webex) - [Google Chat 7](https://actionlake.com/connectors/google-chat) - [Google Cloud Pub/Sub 3](https://actionlake.com/connectors/google-cloud-pub-sub) Joins with, on shared entities - [Lark Suite 2](https://actionlake.com/connectors/lark-suite) - [Basecamp 2](https://actionlake.com/connectors/basecamp) - [Zoom 2](https://actionlake.com/connectors/zoom) - [Discourse 2](https://actionlake.com/connectors/discourse) - [Fireflies.ai 2](https://actionlake.com/connectors/fireflies-ai) - [Freshworks Freshchat 2](https://actionlake.com/connectors/freshworks-freshchat) Browse - [All Email & messaging connectors](https://actionlake.com/connectors/category/email-and-messaging) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
