Overview

AI-generated overview

A free, read-only remote MCP server for eDiscovery news and TAR/review statistics calculators, aimed at legal-AI demos and defensibility discussions.

What you can do
Check server health and list the full tool, prompt and resource catalog, plus a demo walkthrough and rendered prompt templates for clients that cannot open MCP prompts directly. Fetch edd:// resource content such as the demo guide, TAR learning path, glossary and news briefs as plain tool results. Search recent eDiscovery, legal-AI and TAR news by topic, tag or date range, and get a top-stories roundup with a Week in Review breakdown. Score coded samples: recall, precision, F1, accuracy and in-sample elusion from a confusion matrix, or control-set recall. Estimate elusion, prevalence/richness and overall TAR recall with Wilson confidence intervals, and size random samples with finite-popula
When to use it
Useful when you want current eDiscovery and legal-AI news, or need quick statistical answers while planning or defending a TAR workflow: how large a sample to draw, how much relevant material may remain in the discard set, what recall a workflow achieved, or where to draw the review cutoff. Also handy for guided demos of the server.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables or headers declared, and no authentication declared. Network access to the endpoint is needed.
Before you install
Calculators take aggregate counts only and the server states it is not legal advice; treat outputs as inputs to human review, not conclusions. News and resource content is third-party material. Read-only tools, so no data is written or deleted, but queries and counts are sent to the remote endpoint.

Installation

In SourceWeft

  1. Open eDiscovery Decoder News/Calc in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.ediscoverydecoder%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

ping

Ping

Health check: confirm the eDiscovery Decoder News/Calc MCP server is reachable before a demo or when troubleshooting a connection. Returns server name and version. No inputs.

Takes no parameters.

list_capabilities

List eDiscovery Decoder MCP Capabilities

List the full eDiscovery Decoder MCP surface — every tool, prompt, and resource, plus the suggested demo flow and safety boundaries — with an example prompt for each. Call this first when you are unsure which tool fits the user's question, or when tool-search shows only a partial list.

Takes no parameters.

get_demo_guide

Get eDiscovery Decoder MCP Demo Guide

Return a short, human-readable walkthrough for testing this server: the endpoint, the tool/prompt/resource names, and ready-to-paste sample prompts. Use to give someone a guided demo. For the full machine-readable capability catalog, use list_capabilities instead.

Takes no parameters.

get_resource_content

Get MCP Resource Content

Fetch the JSON behind a supported edd:// resource — the demo guide, TAR learning path, glossary, or news (latest / brief / by-date). Use when you want resource content but the client cannot read MCP resources directly, e.g. to pull glossary definitions or the news brief as a normal tool result.

Parametersurirequired

get_prompt_template

Get MCP Prompt Template

Return the rendered text of one of this server's guided prompts (mcp-demo-tour, tar-matter-kickoff, weekly-digest). Use when the client can call tools but cannot open MCP prompts directly, or when you want to inspect a prompt's wording before using it.

Parametersaudienceweek_startprompt_namerequiredmatter_description

search_news

Search eDiscovery News

Find recent eDiscovery / legal-AI / TAR news by topic, tag, or date range. Use when the user asks what's new or recent in eDiscovery, wants stories on a subject, or asks about a time window. For a ready-made top-stories roundup instead, use get_news_brief.

Parameterstagslimitquerydate_todate_from

get_news_brief

Get eDiscovery News Brief

Get the current eDiscovery Decoder news brief: top stories plus a Week in Review breakdown, returned both as structured data and as display-ready Markdown (formatted_brief) with a 'why it matters' line per story. Use when the user wants a roundup or summary of current eDiscovery AI news rather than a keyword search.

Parametersweek_limitcurrent_limit

calculate_review_metrics

Calculate Review Metrics

Score a coded sample when you have a full confusion matrix (true/false positives and negatives) — e.g. comparing a TAR model's calls against a reviewer's. Returns recall, precision, F1, accuracy, and in-sample elusion. Use calculate_control_set_recall if you only have relevant-found vs relevant-missed; calculate_elusion for a discard/null-set sample. Aggregate counts only; not legal advice.

Parameterstrue_negativesrequiredtrue_positivesrequiredfalse_negativesrequiredfalse_positivesrequired

calculate_elusion

Calculate Elusion

Estimate how much responsive/relevant material may remain in a set you chose NOT to review (the discard, null, or 'elusion' set). Use when a random sample of that excluded set has been coded — e.g. 'we sampled 400 culled docs and found 2 relevant.' Returns the elusion rate and a Wilson confidence interval. For an overall recall % from the same sample, use calculate_tar_recall_estimate. Aggregate counts only; not legal advice.

Parameterssample_sizerequiredconfidence_levelrelevant_found_in_samplerequired

calculate_sample_size

Calculate Sample Size

Work out how many documents to randomly sample to estimate a proportion (e.g. richness or elusion) at a target confidence level and margin of error, with finite-population correction. Use when planning a sample before review — 'how big a sample do we need?' Aggregate inputs only; not legal advice.

Parametersmargin_of_errorrequiredpopulation_sizerequiredconfidence_levelestimated_prevalence

calculate_tar_recall_estimate

Calculate TAR Recall Estimate

Estimate overall TAR recall and how many responsive docs were missed, by combining the responsive count already found with an elusion sample of the excluded set. Use when the user wants a recall % for the whole workflow, not just the elusion rate. For only the elusion rate and its interval, use calculate_elusion. Aggregate counts only; not legal advice.

calculate_prevalence_richness

Calculate Prevalence Or Richness

Estimate how rich or prevalent a population is — the share that is responsive/relevant/positive — from positive hits in a random sample, with a Wilson confidence interval. Use for 'what % of this set is relevant?' or to size review scope and cost expectations. Aggregate counts only; not legal advice.

Parameterssample_sizerequiredpositive_hitsrequiredpopulation_sizeconfidence_level

calculate_control_set_recall

Calculate Control Set Recall

Calculate recall against a known control set: the share of documents already confirmed relevant that the workflow found, with a Wilson confidence interval. Use when you have relevant-found and relevant-missed counts from a fixed reference set. For recall from a confusion matrix use calculate_review_metrics; from a discard-set sample use calculate_tar_recall_estimate. Aggregate counts only; not legal advice.

Parametersrelevant_foundrequiredrelevant_missedrequiredconfidence_level

compare_tar_cutoffs

Compare TAR Cutoffs

Compare candidate TAR score or rank cutoffs side by side: for each cutoff, how many docs sit above it, its share of the scored set, and (if responsive counts are given) an estimated precision. Use when deciding where to draw the review/cull line. Aggregate counts only; not legal advice.

Parameterscutoffsrequiredscored_document_countrequired

validate_sample_design

Validate Sample Design

QC a TAR validation sampling plan: check whether it has the documented elements needed for a defensibility discussion (population, sample size, confidence level, sampling frame/method, randomization, etc.) and flag what is missing or inconsistent. Use to sanity-check a sampling protocol before relying on it. Reviews metadata only — not a legal sufficiency opinion.
