To stop an AI agent from making unauthorized wiki changes, enforce its limits through the wiki’s permissions, connector policy, or tool-execution layer—not just a prompt. Give the agent a separate identity, start with read-only access, narrowly scope any required write permissions, and put consequential edits behind review. Then log activity and test that you can revoke access.
Put the boundary outside the agent’s instructions
An instruction such as “do not edit the wiki” is not an access control. If the agent’s account or connected tool can write, a mistaken request or manipulated model may still result in a change. Enforce authorization where the wiki, connector, or tool executes the action. OWASP recommends reducing permissions and limiting the commands or network paths available to a model; see its guidance on generative AI security.

Use several layers where available: the wiki decides which content the identity can access, the connector limits which operations it exposes, and a deterministic check or approval step blocks risky actions before execution. A control is only useful if it applies to the actual integration and credential in use.
Set up access in a safe order
- Map the connection. Record the agent identity and owner, the connector or MCP server, credential type, wiki spaces or pages in scope, and every tool that can create, edit, delete, or change permissions. Authentication method can affect which controls apply.
- Start with read-only access. If the agent only needs to answer questions or prepare a draft, grant the necessary read access without edit rights where supported. Add write access only for a defined workflow, and scope it to the smallest set of resources and operations the system allows.
- Create a dedicated identity. Do not give an agent an administrator’s personal account, browser session, or broad token. Use an identity that can be recognized in logs, with a named owner, documented purpose, approved data scope, and allowed tools. Microsoft recommends treating agents as distinct identities, applying least-privilege scopes, allowlisting actions, logging activity, and supporting revocation: Microsoft Entra Agent ID best practices.
- Gate consequential writes. Require a deterministic policy check or human approval before publication, deletion, permission changes, or edits to protected pages. If the agent platform supports pre-action hooks, use them to deny out-of-scope actions and record approvals rather than relying on the model to self-police.
- Use native wiki protections. Apply page or space restrictions in addition to the agent’s narrow account. Platform-specific examples are below; the exact controls vary by wiki and integration.
- Monitor and rehearse revocation. Log the agent identity, effective scope, requested action, target resource, and outcome. Test disabling the identity and revoking or rotating credentials; repeat the check when the tools, workflow, or data scope changes.
Confluence through Atlassian MCP: check the credential type
Atlassian documents an organization data security policy that can allow or block AI access to Jira and Confluence through MCP. For Confluence, the policy can make covered pages, spaces, and classified content unavailable to agents when access is blocked. However, the policy applies to OAuth authentication, not API-token authentication. When MCP access is allowed, the connected user’s existing permissions govern the content the agent can access. Atlassian also notes that some non-content operations may remain available when content access is blocked. See Atlassian’s documentation on managing AI app access to organization data.

Therefore, identify whether the deployed MCP connection uses OAuth or an API token, then test both content access and available operations using that exact connection. Do not assume the policy blocks an API-token integration or every action an agent can take.
MediaWiki: combine bot accounts with page protection
For MediaWiki, use a bot account rather than an administrator’s personal account, and restrict that account to its actual task. MediaWiki’s bot manual describes bot accounts and the use of edit tokens. Its editing guidance calls for obtaining the edit token and current revision information—including timestamps—before preparing an edit, which helps ensure the change is based on the latest page state.
Where a page needs stronger safeguards, use page protection to restrict editing or moving by user group, such as limiting edits to autoconfirmed users or moves to administrators. Protection complements a narrowly scoped bot account; it does not replace deciding which pages and actions the agent should be allowed to use.

Some agent frameworks expose tool permissions and lifecycle hooks that developers can use to check actions, write audit records, or request approval. GitHub documents these capabilities for its agent tooling: GitHub Copilot extension SDK documentation. Treat hooks as an implementation option, not a guarantee that every platform provides equivalent safeguards or enables them by default. The wiki and connector permissions should still prevent access that the workflow does not require.

Compare integrations on the controls that matter
| What to check | Question to ask |
|---|---|
| Permission granularity | Can access be scoped by wiki, space, page, operation, and agent identity? |
| Enforcement point | Will the wiki, connector, and tool-execution layer each deny an unauthorized write? |
| Credential behavior | Do the same policies apply to OAuth, API tokens, and delegated user sessions? Atlassian documents an OAuth/API-token exception for its MCP access policy. |
| Approval and recovery | Can risky edits require review, and can the identity, permissions, or credentials be disabled or revoked quickly? |
| Auditability | Can an operator connect each edit to the agent identity, effective scope, action, target resource, and outcome? |
Verify the safeguards before relying on them
Run a controlled check with the actual agent connection: confirm it can read only the intended content, attempt an out-of-scope edit in a safe test area, and verify the platform denies it or routes it for approval. Confirm that logs identify the agent and target resource. Finally, disable the identity or revoke its credential and check that the connection no longer works. Repeat these checks after permission, credential, or integration changes.
