Every general Checkfu REST request requires the dated `Checkfu-Version` header (one of: 2026-08-31); the three MCP JSON-RPC transports use `MCP-Protocol-Version`, A2A uses `A2A-Version`, and the provider OAuth callback carries neither Checkfu header. API keys resolve one Workspace without a request selector; authenticated responses identify it with `Checkfu-Workspace-Id`. servers: - url: https://api.checkfu.com security: - bearerAuth: [] tags: - name: organizations - name: sourceRepositories - name: tenants - name: workspaces - name: principals - name: principalGroups - name: principalAccessCredentials - name: apiKeys - name: agents - name: harnesses - name: harnessRuntime - name: permissionAssignments - name: actionPolicies - name: files - name: memoryStores - name: dreams - name: modelCredentials - name: modelRoutingProfiles - name: blueprintInstallations - name: toolSources - name: skills - name: skillSources - name: agentBlueprints - name: skillProposals - name: instructionProposals - name: catalog - name: managedTools - name: concepts - name: support - name: bootstrapRequests - name: connections - name: connectionVaults - name: connectionAssignments - name: connectedRuntimes - name: fileTrees - name: collaboration - name: automationGraphs - name: automations - name: actionApprovals - name: standingApprovals - name: workloadReviewPolicies - name: usage - name: models - name: outcomes - name: budgets - name: billing - name: sessions - name: audit - name: sessionExports - name: runs - name: runnerPools - name: transcripts - name: sessionWatches - name: sessionHandoffs - name: sessionCapsules - name: sessionTrajectories - name: webhookEndpoints - name: integrationGateway - name: workEnvironments - name: computers - name: computerScreens - name: computerBrowserObservations - name: computerBrowserActions - name: environments - name: computerHeadlessOperations - name: vaults - name: apiMcp - name: a2a paths: /v1/managed-tools: get: tags: - managedTools summary: List published Managed Tool releases description: >- Returns a bounded page of exact published releases with input and output schemas. Filter by managed_tool_id to inspect that tool's release history. Metadata and discovery grant no execution authority or commercial eligibility; quoting and invocation separately check grants, supply, price and limits. Revoked releases remain visible so saved configurations can explain their state. No upstream account or customer Connection is required for discovery. Checkfu support posture: preview; hosted.
