StewAI MCP server

• Registry namecom.stewai/stewaiverified in the MCP registry

The registry name sits under stewai.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 608 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• check_recipe_build

  Run free deterministic lint, render, policy, and compiler checks. Omit fixtures for the normal structural check; a supplied fixture probe must also provide every referenced upstream dependency value.

• commit_recipe_build

  Preflight and privately publish only the exact fully qualified recipe revision. A successful commit returns a private editor URL and, when current run access permits it, a recipe_ref. Preview that reference before any dry run: authoring…

• discover_stewai

  Learn how any MCP agent can authenticate, discover, preview, run, author, qualify, commit, inspect, and recover StewAI recipes. Call this first.

• get_recipe_build

  List or inspect only the authenticated creator's private recipe builds. To list builds omit both build_ref and view; limit/cursor paginate that list. With or without build_ref, use view='authoring_schema' and…

• get_recipe_build_activity

  Poll a review or acceptance batch through a bounded, disclosure-safe view.

• get_recipe_preview

  Inspect a safe summary with bounded method and limitations excerpts, output-contract state, and evidence context. For complete authorized published details and executable contracts, use view=details. Concatenate content fragments in…

• get_results

  After a finished run, read view=steps with detail=full first and follow next_cursor; every step the user paid for is part of the result. Declared outputs are the pinned summary, not the whole result. Read declared outputs or a sanitized…

• get_run

  Read an owned run, view=history to resume normal runs (recipe_ref/status/cursor/limit), or view=diagnostics for its settled UI receipt. Default status requires run_id and includes live progress: updated_at is the run record time…

• review_recipe_build

  Quote or run a bounded semantic quality review of the exact private draft revision.

• run_recipe

  Estimate or run a previewed public or account-authorized published recipe. dry_run foregrounds history (recent charges or median and p90), fees, balance, and can_start. safety_ceiling_credits is a pathological bound when available, not a…

• run_recipe_acceptance

  Quote or run selected or complete behavioral acceptance cases for an exact private draft revision. Quotes explain enforced input bounds, output caps and retry allowances in acceptance_cost. Preserve representative fixtures and assertions…

• search_recipes

  Find safe public recipes and published recipes available to the current account. results are direct fits (exact or strong); related_results are adjacent recipes, not direct fits. Each row states its output contract, past-run cost history…

• start_recipe_build

  Create a private recipe build from a bounded intent and declared contract. Recipe inputs are strings: use type:string, positive maxLength, and only minLength:1 on required inputs. Richer input constraints must be handled in recipe logic…

• update_recipe_build

  Apply bounded optimistic changes to an owned private recipe build. After an uncertain response, inspect the build and replay the identical request with the same idempotency key; a new key duplicates the work. Use only the exact op names…
