### Description (declared)

# Redacted Context MCP

Give coding agents useful local project context without exposing raw client
names, people, email addresses, URLs, phone numbers, secrets, or meaningful
filenames.

`redacted-context-mcp` is a read-only-by-default MCP server and CLI. It lets an
agent search, navigate, and read useful content from a private local folder
while replacing sensitive text and returning opaque file references.

Before redaction:

```text
Client Example Lantern Labs uses production-db.internal.example
Contact avery@example.com about PROJECT-LANTERN-042.
```

Agent-visible result:

```text
Client [ORG_a81f29d4a9c1e672540f68afc10d22c7] uses [DOMAIN_d12c88e1f730065c97d3f82f06d1188c]
[ENTITY_6775c54c5116ff547754d1ac0ec5c577] [EMAIL_711ae704108cd6e952dcb27f0d6e999a] about [SENSITIVE_45f80ab22bc94e105a93aa830c7d3b9c].
```

The placeholder values above are illustrative. Real values are deterministic
for one local vault salt and will differ.

This is the default `strict` mode, which also redacts capitalized words and
acronyms that are not on the allow list, such as `Contact` here. `--mode
balanced` skips those two passes and leaves `Contact` as it is.

## How It Works

The agent never opens the private folder itself. It calls `redctx_*` tools,
the server reads the raw files or configured GitHub issues, redacts every
content field at one boundary, and returns only redacted text with opaque
references such as `@p_1a2b3c4d5e6f`.

In the diagrams, blue is the agent side, purple is processing inside redctx,
amber is a check, green is redacted output or success, red is raw private data
or a refusal, orange is a human step, explicit opt-in, or softer guardrail, and
grey is a non-sensitive store.

*This diagram is shown in the [README on GitHub](https://github.com/zoltan0803/redacted-context-mcp#readme).*

Placeholders and path ids are deterministic for one vault salt, so the agent
can follow the same name or file across calls. Only the local operator can
turn them back into raw tex…
