The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
delete-componentDelete a component from a draft workflow, removing all links to and from the component.
list-sessionsGet a paginated list of all execution sessions for a workflow, including session IDs, status, timestamps, and execution mode. Can filter between production and test runs of draft workflows. Returns user-friendly messages when no sessions exist, with pagination support for workflows with many executi…
get-sessionterminate-entire-sessionImmediately stop and terminate an entire workflow session, ending execution of all active components and preventing any further processing. Useful for canceling long-running workflows or stopping erroneous executions. Returns confirmation of termination status.
terminate-componentSelectively terminate a specific component thread within a workflow session while allowing other components to continue running. Provides granular control over workflow execution by targeting individual components or threads. Useful for stopping problematic components without affecting the entire wo…
retry-failed-componentRestart execution of a failed component and continue the workflow from that point forward. Automatically resumes processing from the specified component using existing session data and placeholder values. Essential for recovering from transient failures or errors without restarting the entire workfl…
list-tablesGet a paginated list of all tables for the authenticated client. Returns table summaries including table IDs, names, and pagination controls for browsing through all available tables.
get-tableRetrieve detailed information about a specific table including its ID, name, and complete column definitions. Provides the full schema and metadata for the specified table.
create-tableCreate a new Table with the given name and columns
add-columnAdd a column to an existing table.
rename-columnRename a column in an existing table.
delete-columnDelete a column from an existing table.
list-tasksGet a filtered list of task summaries with comprehensive filter options including text search, workflow filtering, status filtering, date range filtering, and pagination support. Returns task details with names, descriptions, URLs, workflow information, and navigation links for easy task management …
list-formsGet a paginated list of available forms including form names, URLs, associated workflow IDs and names. Returns form metadata with pagination support for easy form discovery and access. Useful for finding forms that users can submit or access.
list-workflowsGet a paginated list of workflow summaries including workflow IDs, names, publication status, draft versions, and navigation links. Returns structured metadata for each workflow with pagination controls and links to detailed workflow information.
get-workflow-historyRetrieve a paginated history of all versions for a specific workflow, including version numbers, timestamps, status changes, and metadata for each version. Useful for tracking workflow evolution and accessing previous versions.
get-workflowGet comprehensive workflow details including metadata (ID, version, status, name), full workflow description with purpose and use cases, complete component definitions with types and descriptions, placeholder mappings for data flow between components, component connections and relationships, and lin…
run-workflowrerun-workflowpublish-workflowPublish an existing workflow DRAFT, making it available for production execution. Adds a comment and description to document the publication. Creates a new published version and increments the draft version number.
unpublish-workflowUnpublish an existing workflow, making it unavailable for normal execution. This changes the status of the currently published version and makes only the draft version available. Useful for taking workflows offline for any reason.
update-workflow-detailsUpdate workflow name and/or description. Only provided fields will be updated, omitted fields will remain unchanged.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Undici: Malicious WebSocket 64-bit length overflows parser and crashes the client
Undici has Unhandled Exception in WebSocket Client Due to Invalid server_max_window_bits Validation
W86_API_KEYW86_DOMAINOptional: set to point at a different API host (defaults to https://api.workflow86.com).W86_HEADERSTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
22/22 tools missing one or more hints — delete-component (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list-sessions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
12/22 tool handlers declare input schemas (55%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Secrets not logged
1 secret value sent to error
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 7 high severity in production deps — @modelcontextprotocol/sdk@1.17.5 (high), @modelcontextprotocol/sdk@1.17.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Domain consistency
npm scope @npm-workflow86 doesn't match GitHub owner workflow86oss
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
