Tilden Workspace MCP — read-only AI client connection

01 · Access

Start with your invited Workspace

You need an active invited Workspace, owner or admin access, and MCP enabled for that Workspace. Your onboarding contact helps confirm the client version and connection flow. Joining the waitlist does not immediately enable a Workspace or this endpoint.

02 · Connect

Add the Workspace endpoint

Remote MCP server URL

https://app.asktilden.com/api/workspace/mcp

In the client selected during onboarding, add a remote HTTP MCP server using the URL above.
Start the client's sign-in flow and sign in with your invited owner or admin account.
On the Tilden consent screen, check the app name, Workspace and read-only access before choosing Allow access.
Return to the client and confirm that the four Workspace tools appear. Read a report and compare it with Workspace using the same dates and accounts.

Use the canonical URL exactly. Provider API keys, browser cookies and machine-sharing credentials are not MCP login credentials. The client follows the server's OAuth sign-in flow; provider keys stay out of the client configuration.

03 · Read reports

Four read-only tools

workspace_spend

Read retained cost data, evidence labels and missing-data coverage for selected dates and accounts.

workspace_projects

Read the project cost groups in the same Workspace report. Provider projects do not establish repository ownership or agent outcomes.

workspace_briefing

Read the spending summary, available comparisons and investigation suggestions with their evidence and coverage.

workspace_budgets

Read configured monthly budgets and their settings. Budget evaluations, reached thresholds and alert history are not included.

Spend, projects and briefing accept inclusive UTC start and end dates, plus optional connected account IDs within the consented Workspace. Budget reads return settings in pages. All tools read retained records; none triggers a provider refresh.

Example request

Show my Workspace spend for September 1–30, 2026.
Name the included accounts and currency. Keep provider-reported costs,
estimates and missing coverage separate. Show the largest reported
project groups and one question worth investigating.
Do not infer per-person spend, savings or ROI from activity.

When separately enabled, Cursor and Copilot results retain their own periods and estimate labels. They are not added to the OpenAI/Anthropic cost report, its comparison, or each other. An unavailable report is not a zero-dollar result.

04 · Manage access

Approval grants read-only access for seven days. Access-token refresh does not extend that grant. For an expired connection, follow the reconnect and expired-access recovery steps before another review. Open Settings → Apps to identify the client and check the recorded result; stop if the outcome is uncertain.

Removing access stops future authorized reads. It cannot erase results an AI client already received. Those results follow the client's data policy. A fresh connection after removal may also require resetting that app's sign-in consent, as explained in Settings.

05 · Troubleshooting

Check the connection and the evidence

Sign-in does not finish: Return to the client and use its normal sign-in flow. Confirm the invited account and client version with your onboarding contact.
Access is unavailable: Check that Workspace MCP is enabled, your owner or admin membership remains active, and the app connection has not expired or been removed.
A report is unavailable: Check the requested dates, selected accounts and source coverage in Workspace. MCP reads existing records and cannot create missing provider data.
The answer differs from Workspace: Compare the same period and accounts, then inspect the returned evidence labels and coverage. An AI-generated answer can omit qualifications present in the tool result.
