Claude Code Connector Permissions: Review the Real Scope

Claude Code connector permissions: understand the access path, warning signs, safe checks, and controls before your next sensitive task.

CapitalGuard Security ResearchUpdated July 13, 2026Primary-source review

The direct answer

MCP servers and hooks can expose local commands, files, APIs, tokens, and external services to the agent. Claude Code only has the permissions granted to it, but broad read access, bypass modes, unsandboxed commands, or overpowered MCP servers can make that boundary much wider than expected.

What changes here

How Claude Code creates this exposure

Claude Code is a local or cloud coding agent with file, command, network, MCP, and editing capabilities governed by permissions, sandboxing, trust, and account settings.

A connector does not create data, but it can make existing account permissions available through a new interface. The safe question is not only whether the connector is trusted; it is whether the connected account is broader than the task requires.

MCP servers and hooks can expose local commands, files, APIs, tokens, and external services to the agent.

The exposure path

Three steps from useful context to avoidable risk

  1. 1

    Context enters

    MCP servers and hooks can expose local commands, files, APIs, tokens, and external services to the agent.

  2. 2

    Access carries it

    Claude Code may use repository and local file reads, edits and Bash commands, or network access, MCP servers, hooks, and cloud environments, depending on the surface and settings.

  3. 3

    A real consequence becomes possible

    A personal connector may expose private mail, files, contacts, calendar details, browsing context, or shared documents that were never intended for the current conversation. A business connector can turn an over-privileged account into a broad retrieval or action surface spanning customers, employees, projects, and internal operations.

This page does not claim that Claude Code has exposed your information. It shows the access conditions that make a review sensible before the next sensitive task.

Warning signs

Pause before adding more access

The authorization screen requests broad scopes and nobody recorded why each one is needed.

Read, create, edit, share, send, and delete actions are enabled together by default.

A connector remains active after a project ends or after the user’s role changes.

Five-minute safe check

Check Claude Code without exposing more data

Review .mcp.json, managed settings, hooks, server commands, scopes, transports, and trust prompts.

Review the connector’s exact scopes in both the AI tool and the source service.

Test with a limited account containing synthetic data before connecting a primary mailbox or drive.

Confirm how to disconnect, revoke tokens, remove indexed copies, and review prior actions.

Reduce the risk

Controls to apply now

Remove unknown servers and sandbox each remaining integration with narrow paths and network destinations.

Use a least-privilege account or service identity created for the specific workflow.

Separate read-only retrieval from write, send, share, delete, and financial actions.

Set a recurring owner and expiry date for every connector rather than leaving access permanent.

Review permission mode and deny rules.

Review filesystem and network sandbox.

Review trusted directories, mcp servers, hooks, and unsandboxed escape paths.

Decision rule

When CapitalGuard is the right next step

If the assistant has no connectors, document that and keep it true. If it can retrieve or change business data across services, create an access map before adding another integration.

CapitalGuard focuses on repository and tool-connected exposure: what an AI workflow can read, change, execute, trust, or transfer. It does not inspect your private Claude Codeaccount from this page, replace the provider's privacy controls, or guarantee that an incident can never happen.
