# bar_plot Create a bar chart from CSV or Excel data with categorical grouping. Agent View of the PolicyLayer registry record for `bar_plot`. HTML page: https://policylayer.com/tools/io-github-iowarp-adios-mcp/bar-plot ## Facts - Tool: `bar_plot` - Server: CLIO Adios (`pypi:clio-kit`) — https://policylayer.com/tools/io-github-iowarp-adios-mcp.md - Install: `npx -y pypi:clio-kit` - Homepage: https://github.com/iowarp/clio-kit - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "bar_plot", "arguments": {} } } ``` ## Why bar_plot is rated Medium The bar_plot tool creates visualization outputs (bar charts) from input data. While it doesn't modify the original data source and has no destructive effects, it does generate new data artifacts (the chart itself), making it a Write operation. The severity is low because misuse would only result in incorrect visualizations with minimal blast radius—no financial impact, data loss, or system compromise possible. From the tool's own definition: "The tool 'Create a bar chart' takes input data and generates a visualization artifact (chart). This is a data creation/generation action that produces new output." ## Use case AI agents use bar_plot to create or update resources in CLIO Adios, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CLIO Adios environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CLIO Adios: ```json { "version": "1", "default": "deny", "tools": { "bar_plot": { "limits": [ { "counter": "bar_plot_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on CLIO Adios (203) - `cancel_slurm_job` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/cancel-slurm-job.md - `destroy_pipeline` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/destroy-pipeline.md - `jm_remove_repo` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/jm-remove-repo.md - `jm_reset` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/jm-reset.md - `remove_pkg` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/remove-pkg.md - `slurm_cancel` — Destructive — https://policylayer.com/tools/io-github-iowarp-adios-mcp/slurm-cancel.md - `allocate_slurm_nodes` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/allocate-slurm-nodes.md - `build_pipeline_env` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/build-pipeline-env.md - `generate_isosurface` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/generate-isosurface.md - `heatmap_plot` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/heatmap-plot.md - `hypothesis_testing` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/hypothesis-testing.md - `jarvis_run` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/jarvis-run.md - `jm_cd` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/jm-cd.md - `jm_graph_build` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/jm-graph-build.md - `module_load` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/module-load.md - `module_swap` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/module-swap.md - `module_unload` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/module-unload.md - `parallel_sort_large_file` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/parallel-sort-large-file.md - `reset_camera` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/reset-camera.md - `rotate_camera` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/rotate-camera.md - `run_pipeline` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/run-pipeline.md - `show_screenshot_preview` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/show-screenshot-preview.md - `stop_chronolog` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/stop-chronolog.md - `submit_array_job` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/submit-array-job.md - `submit_slurm_job` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/submit-slurm-job.md - `warp_by_vector` — Execute — https://policylayer.com/tools/io-github-iowarp-adios-mcp/warp-by-vector.md - `aggregate_column_tool` — Read — https://policylayer.com/tools/io-github-iowarp-adios-mcp/aggregate-column-tool.md - `analyze_file_access_patterns` — Read — https://policylayer.com/tools/io-github-iowarp-adios-mcp/analyze-file-access-patterns.md - `analyze_log_statistics` — Read — https://policylayer.com/tools/io-github-iowarp-adios-mcp/analyze-log-statistics.md - `analyze_mpiio_operations` — Read — https://policylayer.com/tools/io-github-iowarp-adios-mcp/analyze-mpiio-operations.md - …and 173 more: https://policylayer.com/tools/io-github-iowarp-adios-mcp.md ## For agents This record is a snapshot.
