Use MCP servers with Paperclip

Paperclip works with MCP in both directions. Your agents can use any MCP server, with a rule for each action. Your own assistant can also control Paperclip through Paperclip’s MCP server.

How do Paperclip agents use an MCP server?

Open Connectors in Paperclip and choose Connect your own MCP server. Paste the server’s URL. Paperclip asks the server how to sign in, lists its actions and lets you set a rule for each one. You also choose which people and agents may use the connection.

  • Each action is Allowed, Ask first or Off
  • Ask first turns a tool call into a decision for a person
  • Paperclip keeps a record of the calls
  • Your whole team shares one connection, and you choose which people and agents may use it

Connect an MCP server for your agents

You need the server’s http or https URL.

  1. Add the server

    Open Connectors and choose Connect your own MCP server. Paste the URL.

  2. Sign in

    Paperclip detects what the server needs. It runs an OAuth sign-in in the browser, asks for a key or connects with no sign-in.

  3. Set a rule for each action

    Paperclip sorts the actions into read, write and destructive. Set each one to Allowed, Ask first or Off.

  4. Choose who can use it

    Pick the people and agents that may use the connection. After the server changes, choose Refresh actions.

Two paths

Connector or agent config: which one should I use?

On the Legacy runner, an agent can also use MCP servers from its own config file. The two paths behave differently.

Servers in an agent’s own config are not guaranteed to load in a Paperclip run. On Paperclip Runner, each session uses an isolated home. Use a connector when you can.

Paperclip as a server

Does Paperclip have its own MCP server?

Yes. Each Paperclip instance can serve MCP at /mcp/paperclip. With it, an assistant such as Claude Code or Codex can list agents, create tasks, add comments and read results. The feature is experimental and off by default.

  • An instance admin turns it on in Settings, under Experimental
  • Sign-in uses OAuth, and a person approves one organization
  • The assistant can list pending approvals, but a person decides them in Paperclip

Guide

Connect Claude Code or Codex to Paperclip

Your instance needs sign-in accounts (authenticated mode) and an address the assistant can reach. Replace YOUR-PAPERCLIP-HOST with that address. Public use needs HTTPS.

  1. Turn the feature on

    An instance admin opens Settings, then Experimental, and turns on Assistant connections (MCP).

  2. Add Paperclip to Claude Code

    Run this command, then open /mcp in Claude Code to sign in.

    Terminal
    claude mcp add --transport http paperclip https://YOUR-PAPERCLIP-HOST/mcp/paperclip
  3. Or add Paperclip to Codex

    Add the server, then sign in with the scopes you want.

    Terminal
    codex mcp add paperclip --url https://YOUR-PAPERCLIP-HOST/mcp/paperclip
    codex mcp login paperclip --scopes paperclip:read,paperclip:write,paperclip:configure,offline_access
  4. Approve the connection

    Follow the approval link and choose Connect organization. Then ask the assistant to call paperclip_connection to check that it works.

Limits

What should I know before I start?

The two directions have different rules. A connector is governed by Paperclip. A server in an agent’s own config is not. Paperclip’s own MCP server is experimental.

  • Servers outside the reviewed catalog show as Unverified server
  • Work that an assistant starts through MCP uses Paperclip’s agents and budgets
  • You can revoke an assistant connection on the Connectors page

FAQ

Questions about Paperclip and MCP

Can my Paperclip agents use any MCP server?

Yes. Add it by URL on the Connectors page and set a rule for each action.

Do my Claude Code MCP servers still work in Paperclip?

Not reliably. On Paperclip Runner, each session uses an isolated home, so servers in your own Claude Code config may not load. Add the server as a connector instead.

How do I connect Claude Code or Codex to Paperclip?

Turn on Assistant connections, then add https://YOUR-PAPERCLIP-HOST/mcp/paperclip as a remote MCP server. The steps are above.

Can an assistant approve work for me through MCP?

No. It can list pending approvals and link you to Paperclip. You make the decision there.

Is paperclip.ing/mcp the same thing?

No. That address serves read-only information about this website. It does not connect to any Paperclip instance.

“Give an agent a tool and a rule for each action. The agent moves fast on the safe actions, and a person decides the rest.”
