Model Context Protocol server for Rollbar
Lead Green is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
GPU energy per million output tokens by model, GPU and configuration, with grid carbon by country.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user lead-green-mcp '--' uvx leadgreen-mcp
# 2 — ask your agent for something these tools do
# list_models, energy_per_million_tokens, estimate and 5 more
Lead Green costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Lead Green as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. You need uv (docs.astral.sh/uv): uvx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user lead-green-mcp '--' uvx leadgreen-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
8 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
List every model on the Green Tokens index with the GPUs it was measured on.
No parameter schema on file.
GPU energy per million output tokens for a model, from the index.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| model | string | yes | model name, slug or Hugging Face id (for example "Qwen 3 32B", "qwen-3-32b" or "Qwen/Qwen3-32B"). |
| gpu | string | no | optional, "H100" or "B200". If omitted, every GPU the model was measured on is returned. |
| itl_deadline_ms | number | no | optional latency ceiling in milliseconds. If given, each GPU's row is re-selected from every measured configuration: the lowest energy whose median inter-token latency is at or under it. If omitted, t |
Estimate GPU energy, and optionally carbon and energy at the meter, for serving a number of output tokens.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| model | string | yes | model name, slug or Hugging Face id. |
| output_tokens | number | yes | how many output tokens will be generated (for example 50_000_000 for fifty million). |
| gpu | string | no | "H100" or "B200". If omitted, the most efficient measured GPU is used. |
| country | string | no | optional country name or ISO 3166 code (or "World") to convert the energy to kg CO2e using that grid's annual average intensity. |
| running_batch | number | no | optional. The average running batch the server will hold: how many requests it decodes at once (vLLM num_requests_running). If given, the estimate uses the measured configuration nearest to it, on the |
| num_gpus | integer | no | optional. Use configurations on this many GPUs (for example 2 for 2 x H100). |
| itl_deadline_ms | number | no | optional latency ceiling in milliseconds. The lowest-energy configuration with median inter-token latency at or under it is used. If omitted, the index's own ceiling applies. |
| pue | number | no | optional power usage effectiveness of the facility, at least 1.0. |
| system_power_ratio | number | no | optional ratio of whole-server power to GPU power, at least 1.0 (a DGX B200 at its 14.3 kW maximum over 8 x 1.0 kW of GPU power is about 1.79). |
| requests_in_flight | number | no | the old name for running_batch, still accepted. |
Compare a model's energy per million output tokens on H100 and B200.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| model | string | yes | model name, slug or Hugging Face id. |
| itl_deadline_ms | number | no | optional latency ceiling in milliseconds. If given, each GPU's row is the lowest-energy configuration with median inter-token latency at or under it. If omitted, the index rows are compared. |
Energy per million output tokens at every measured running batch for a model on a GPU.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| model | string | yes | model name, slug or Hugging Face id. |
| gpu | string | yes | "H100" or "B200". |
Annual average grid carbon intensity for a country, in g CO2e per kWh.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| country | string | yes | country name (common names such as "UK", "US" or "Turkey" work), ISO 3166 alpha-3 code, alpha-2 code where the data carries it, or "World". |
Manufacturer power ceilings (max TDP), memory, and MIG slice profiles for data-centre GPUs.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| gpu | string | no | optional filter such as "H100", "H200", "A100" or "B200". Omit for all. |
Every source behind the index, with version, retrieval date and licence, plus the API endpoints.
No parameter schema on file.
- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source published under Apache-2.0
- Runs on your machine — nothing of it reaches our gateway
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Lead Green or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| verification-discount | source | publisher verification (provenance) — cryptographic build provenance ties the artifact to its source | −0 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tools were statically extracted from the published source (8 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| list_models | no tags | |
| energy_per_million_tokens | no tags | |
| estimate | no tags | |
| compare_gpus | no tags | |
| concurrency_curve | no tags | |
| grid_intensity | no tags | |
| gpu_hardware | no tags | |
| sources | no tags |
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.3.1. Pin a release below and the command asks for exactly that one.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Lead Green can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
