# save_project Persist a CivilQuants project with its assembly list. Each call creates a new project — it never overwrites an existing one. To revise a saved project's parameters: call get_project to recover its assemblies, amend the values, then call save_project again with the amended list (a revision-suffixed name like 'Pump Station R02' keeps the history browsable) and run recompute_project on the new project_id — recompute_project takes no parameter overrides. To measure a different assembly type instead, route via resolve_assembly_from_description. Re-find saved work in a later conversation with list_projects or get_project by exact name.

HTML page: https://policylayer.com/tools/com-civilquants-civilquants/save-project ## Facts - Tool: `save_project` - Server: Civilquants (`https://api.civilquants.com/mcp`) — https://policylayer.com/tools/com-civilquants-civilquants.md - Homepage: https://github.com/https://api.civilquants.com/mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server rate-limited: no - Parameters: 1 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `request` | object | yes | Body for ``POST /api/v1/mcp/project/save``. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "save_project", "arguments": { "request": {} } } } ``` ## Why save_project is rated Medium save_project creates and stores new estimating projects reversibly. While it never overwrites existing projects (preventing destructive behavior), it does create and modify data within the system. This is a Write operation — data creation/modification with potential to accumulate many saved versions. From the tool's own definition: "'Persist a CivilQuants project with its assembly list. Each call creates a new project — it never overwrites an existing one.' Tool description explicitly states it creates and persists new project data." Risk signals: High parameter count (13 properties) ## Use case AI agents use save_project to create or update resources in Civilquants, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Civilquants environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Civilquants: ```json { "version": "1", "default": "deny", "tools": { "save_project": { "limits": [ { "counter": "save_project_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Civilquants (55) - `compute_box_culvert` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-box-culvert.md - `compute_combined_services_trench` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-combined-services-trench.md - `compute_connection_to_existing` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-connection-to-existing.md - `compute_ditch` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-ditch.md - `compute_embankment_cross_section` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-embankment-cross-section.md - `compute_end_area_earthworks` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-end-area-earthworks.md - `compute_gabion_wall` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-gabion-wall.md - `compute_headwall_attenuation_outlet` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-headwall-attenuation-outlet.md - `compute_highway_drainage_channel` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-highway-drainage-channel.md - `compute_lighting_column` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-lighting-column.md - `compute_multi_section_assembly` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-multi-section-assembly.md - `compute_pad_foundation` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-pad-foundation.md - `compute_parapet` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-parapet.md - `compute_pipe_bedding` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-pipe-bedding.md - `compute_reinforced_soil_wall` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-reinforced-soil-wall.md - `compute_road_marking` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-road-marking.md - `compute_single_service_run` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-single-service-run.md - `compute_soakaway` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-soakaway.md - `compute_soil_nailed_slope` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-soil-nailed-slope.md - `compute_traffic_sign` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-traffic-sign.md - `compute_utility_chamber` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-utility-chamber.md - `compute_utility_kiosk_base` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/compute-utility-kiosk-base.md - `recompute_project` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/recompute-project.md - `render_skill_report` — Execute — https://policylayer.com/tools/com-civilquants-civilquants/render-skill-report.md - `compute_attenuation_tank` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-attenuation-tank.md - `compute_bored_pile_wall` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-bored-pile-wall.md - `compute_cantilever_wall` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-cantilever-wall.md - `compute_carrier_pipe_run` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-carrier-pipe-run.md - `compute_catchpit` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-catchpit.md - `compute_edge_drain` — Read — https://policylayer.com/tools/com-civilquants-civilquants/compute-edge-drain.md - …and 25 more: https://policylayer.com/tools/com-civilquants-civilquants.md ## For agents This record is a snapshot.
