generated: '2026-07-21' method: derived status: candidate source: https://testsigma.com/docs/api/overview/ notes: No official hosted/remote MCP server was found for Testsigma. Testsigma does publish an agent integration — the "Arcus" Claude Code plugin (github.com/testsigmahq/arcus-claude-plugin), which captures Claude Code session context and authors tests into Testsigma — but that is a Claude Code plugin, not an MCP server. The tools below are a CANDIDATE tool list derived from the documented REST API operations, one tool per operation. related_agent_surface: name: Arcus Claude Code plugin repo: https://github.com/testsigmahq/arcus-claude-plugin install: claude plugin marketplace add testsigmahq/arcus-claude-plugin kind: claude-code-plugin server: name: testsigma transport: http tools: - name: list_projects description: List projects and their IDs. source_operation: GET /api/v1/projects - name: list_applications description: List applications and their IDs. source_operation: GET /api/v1/applications - name: list_uploads description: List uploads and their IDs. source_operation: GET /api/v1/uploads - name: list_environments description: List environments. source_operation: GET /api/v1/environments - name: get_environment description: Get a single environment by ID. source_operation: GET /api/v1/environments/{id} - name: create_environment description: Create an environment. source_operation: POST /api/v1/environments - name: update_environment description: Update an environment. source_operation: PUT /api/v1/environments/{id} - name: list_elements description: List test elements/objects. source_operation: GET /api/v1/elements - name: list_test_plans description: List test plans. source_operation: GET /api/v1/test-plans - name: trigger_test_plan description: Trigger a test plan execution. source_operation: POST /api/v1/execution_results - name: get_execution_result description: Check a test plan run's status and result. source_operation: GET /api/v1/execution_results/{run_id} - name: upload_file description: Upload a file (e.g. app build). source_operation: POST /api/v1/upload-files deployment: mode: none verified: derived tools: 12 checked: '2026-08-12' source: catalog MCP census
