polyplan-mcp
Enables structured multi-model AI planning sessions across multiple CLI coding tools, orchestrating independent planning, peer review, and final synthesis.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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.
initInitialize PolyPlan in this project — creates .plans/ and .polyplan/ directories
round_1Start Round 1 — create an independent plan for this model/CLI (no other models seen)
round_1_contextGet the Round 1 prompt — call this first, then generate your plan, then call round_1 to save
round_2Start Round 2 — peer-review all Round 1 plans and write a revised master plan (requires ≥2 Round 1 plans)
round_2_contextGet the Round 2 prompt with all other models' Round 1 plans injected — call this before generating your Round 2 plan
final_planStart Final round — synthesize ALL Round 1 + Round 2 plans into one implementable plan (requires ≥1 Round 2 plan)
final_plan_contextGet the Final round prompt with ALL Round 1 + Round 2 plans injected — call this before generating the final plan
show_statusShow full session state — which models completed each round, open questions, and conflicts
clear_plansDelete ALL plan files across all rounds. Must set confirm=true.
clear_round_1Delete only Round 1 plan files — leaves Round 2 and Final intact. Must set confirm=true.
clear_round_2Delete only Round 2 plan files — leaves Round 1 and Final intact. Must set confirm=true.
show_conflictsShow all points where models disagreed in Round 1 — technology choices, approach, and assumption conflicts
show_questionsShow all open questions raised by any model in Round 1, and whether other models answered them
show_diffShow what changed for a specific model between their Round 1 and Round 2 plans
show_agreeShow what ALL models agreed on independently in Round 1 — highest-confidence decisions
show_summaryOne-paragraph summary of each model's plan — quick overview of all positions
export_plansBundle the entire .plans/ session into one readable markdown file for sharing or archiving
show_historyFull audit log — which model, which CLI tool, which round, what time, what action

Tool 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
18/18 tools missing one or more hints — init (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); round_1 (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); round_1_context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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
16/18 tool handlers declare input schemas (89%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), zod@3.22.0 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
