MCP server for per-agent cost attribution, budget management, and spend analytics across AI agent fleets
Free
Nothing to run from here
Signal Relay 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.

Quickstart
# 1 — run it from where its publisher ships it
npx -y signal-relay-mcp
# 2 — ask your agent something

Signal Relay is free: there is no plan to choose, no cap to set and nothing that can bill you.

Installation
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 Signal Relay 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. It is scanned, signed and pinned to the version you choose — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.
claude mcp add signal-relay-mcp -- npx -y signal-relay-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free to install, and it runs from its publisher’s own package: no account, no key, no card.
What it writes
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.
What you approve
24 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.
[Research/Personas] List available synthetic personas from the SocioLogic marketplace or your private collection. Use this to discover personas for interviews or campaigns.
Takes no parameters.
Example callreturns →
[Research/Personas] Get detailed information about a specific persona including demographics, psychographics, and behavioral traits.
Takes no parameters.
Example callreturns →
[Research/Personas] Create a new AI persona from a natural language description. Returns rich persona data including demographics, psychographics, communication style, and behavioral traits. Use the returned data to role-play as this persona in conversation, or pass it to a subagent for user research interviews.
Takes no parameters.
Example callreturns →
[Research/Personas] Retrieve a persona's semantic memories. Memories are vector-embedded learnings from past interactions that inform future responses.
Takes no parameters.
Example callreturns →

Takes no parameters.
Example callreturns →
[Research/Campaigns] Get detailed information about a specific campaign including status, personas, questions, and interview results.
Takes no parameters.
Example callreturns →
[Research/Campaigns] Create a new research campaign. Define questions and either generate new personas or use existing ones. Campaigns enable systematic multi-persona research.
Takes no parameters.
Example callreturns →
[Research/Campaigns] Execute a draft campaign. This triggers background interviews with all personas and generates a research report. Long-running operation.

Example callreturns →
[Research/Campaigns] Export a completed campaign's results as PDF or JSON. PDF includes executive summary, persona responses, and synthesized findings.
Takes no parameters.
Example callreturns →

Takes no parameters.
Example callreturns →
[Research/Focus Groups] Get detailed information about a focus group including its member personas.
Takes no parameters.
Example callreturns →
[Research/Focus Groups] Create a new focus group to organize personas for cohort-based research.
Takes no parameters.
Example callreturns →
[Research/Focus Groups] Add one or more personas to an existing focus group.
Takes no parameters.
Example callreturns →
[Payments] Check your current credits balance. Credits are used for persona interviews and campaign execution.
Takes no parameters.
Example callreturns →
[Payments] Get x402 payment discovery information. Returns which endpoints accept crypto payments (USDC on Base), wallet address, pricing, and facilitator details.
Takes no parameters.
Example callreturns →
[Search & Scraping] Search the web and return scraped results. Returns markdown content from matching pages.
Takes no parameters.
Example callreturns →
[Search & Scraping] Search a topic and aggregate content from multiple web sources. Returns summarized results useful for building research context.
Takes no parameters.
Example callreturns →
[Utilities] Generate a cryptographically random UUID v4. Useful for creating unique identifiers for experiments, sessions, or tracking.
Takes no parameters.
Example callreturns →
[Utilities] Generate a cryptographically random floating-point number between 0 and 1. Uses hardware entropy for true randomness. Returns a float. Use sociologic_rng_int for integers in a specific range.
Takes no parameters.
Example callreturns →
[Utilities] Generate a cryptographically random integer within a range. Default range is 0-100. Uses hardware entropy for true randomness.
Takes no parameters.
Example callreturns →
[Utilities] Roll a cryptographically random die with a configurable number of sides. Default is a 6-sided die. Uses hardware entropy for true randomness.
Takes no parameters.
Example callreturns →
[Utilities] Flip a cryptographically random coin. Returns heads or tails. Uses hardware entropy for true randomness.
Takes no parameters.
Example callreturns →
[Utilities] Randomly shuffle an array of items using the Fisher-Yates algorithm with cryptographic randomness. Useful for randomizing survey question order, A/B test assignments, or persona selection.
Takes no parameters.
Example callreturns →
[Utilities] Select a random item from an array using weighted probabilities with cryptographic randomness. Useful for simulating demographic distributions, market share splits, or probability-based scenarios.
Takes no parameters.

ATrust score 96 / 100
Release 2.0.0 · scanned 25 Aug 2026
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.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
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.
Tool surfacenot available
Implementation sourceread

Live transportnot available
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>".
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. moderate is the level these add up to.

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.

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.

Only accounts with at least 50 real tool calls against this server in the last 90 days can post. Ratings are weighted by how much the reviewer actually uses it, and publishers can reply once per review.
Reviews are earned
Writing one takes an account with at least 50 real tool calls against Signal Relay in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
No reviews yet
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 an account with 50 real tool calls against it.
