Pack local or remote codebases into AI-friendly files that LLMs and coding agents can read or search
Periscope 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
MCP broker into your live Neovim/diver config: LSP, formatters, linters, DAP, MATE attention.
Quickstart
Install it the way its author documents:

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 Periscope 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.

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.
Alignment between your published focus and a partner agent's focus, measured only inside one saliency snapshot frame (Jaccard overlap, shared targets, shared top). Refused across frames.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| agent_id | yes | — |
Coordination decision against a partner agent's focus: parallel (no contention), serialize (same top target — the named holder proceeds, you defer), or reject (stale frame or invalid focus — re-snapshot, never guess).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| agent_id | yes | — |
Read a partner agent's currently advertised focus (ordered salient targets + the saliency snapshot hash it was computed from) from the coordination board.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| agent_id | yes | — |
Publish your attention focus to the coordination board. The focus document's agent_id must equal your client identity; sequences must strictly advance. Bounded: at most 8 targets.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| focus | object | yes | A focus document: {agent_id, snapshot_hash, seq, targets[]} — ordered salient targets, most salient first. |
Report the broker mode (managed or attached), the editor version, its config root, and its working directory.
No parameter schema on file.
Definitions of the symbol at a position, from the editor's attached language servers, merged across clients.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — | |
| line | yes | — | |
| character | yes | — |
Diagnostics for one file from every source the editor aggregates (language servers and the linter pipeline), each entry naming its producing tool in source.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — |
The symbol outline of one file, flattened with container names, from the editor's attached language servers.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — |
Hover text (types, documentation) for the symbol at a position, from the editor's attached language servers.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — | |
| line | yes | — | |
| character | yes | — |
References to the symbol at a position, merged across the editor's attached language servers.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — | |
| line | yes | — | |
| character | yes | — | |
| include_declaration | boolean | no | — |
The debug setup the config ships: per-language dap modules, adapters registered with nvim-dap right now, and launch configurations by filetype.
No parameter schema on file.
Every formatter in the editor config's registry.
No parameter schema on file.
Every linter in the editor config's registry (internal helpers reported separately).
No parameter schema on file.
Every language server the editor config defines, plus the clients active in the editor right now.
No parameter schema on file.
Format one file with the editor config's own formatter pipeline and return the result. The formatted text is applied to the brokered editor's buffer and returned in text; the file on disk is never written (written is always false). With no formatters, the filetype's configured pipeline runs…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — | |
| formatters | array | no | Explicit formatter names to run, in order. Omit for the filetype's configured pipeline. |
| lsp | string | no | The pipeline's LSP mode. 'only' cannot be combined with explicit formatters. |
Lint one file with the editor config's own linter runner and return per-linter results: status, exit code, and the diagnostics each linter produced (every diagnostic names its linter in source). With no linters, the filetype's configured set runs. Nothing is written to disk.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| path | yes | — | |
| linters | array | no | Explicit linter names to run. Omit for the filetype's configured set. |
- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source is public, though no licence is declared for it
- 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 Periscope 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 | repo | publisher verification (public source) — no provenance, but the source is public and inspectable | −1 |
| coverage-honesty | metadata | inspection depth (metadata) — how much of the target the scan could see | −8 |
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.
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
The implementation source was not read — the published package was fetched but contains no source files the scanner reads.
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 |
|---|---|---|
| No per-tool rows for this release — see the note below. | ||
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
It installs from its repository rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 0.1.0.
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 Periscope 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.
